Macarons a la Pierre Herme

If you ask me where the best macaron in Paris is, I will no doubt say Pierre Herme. Forget Laduree, forget Fauchon. This guy is a genius when it comes to macarons. The shells have the right kind of chewiness and the flavor combinations are creative yet well-balanced (not overly sweet). Another patisserie good enough to rival his in this aspect would be Sadaharu Aoki. But then, you would be looking at a more asian-inspired flavor profile.


Getting the feel of making macarons can be tricky. The first time I made them (in pastry school after a demonstration), they came out fine. Chewy and smooth. The second time I made them, they had little peaks on top. The third and fourth...they came out more like hard cookies and dacquoise respectively. By then, I was getting frustrated. I stayed off them for months and unfortunately I missed out on learning from the Paris pastry shop I interned with. Macarons were off-limits to stagiares (interns).


Tip #1: Get the Batter to the Right Consistency

Two weeks ago, I returned to my home country and early this week I began another internship with a local pastry shop. Surprisingly, they guided me to make macarons on the second day. It was then that I found the key. Although their method was completely different form the one taught in France, the first most important thing is to get the batter to the right consistency. One like magma. What that means is that the batter:

• Should look like thick liquid and flow easily
• Should become smooth several seconds after you cut through it (or make ribbon markings)
• Should be shiny 

Contrary to the general purpose of using meringue, you basically want to beat the air out of them. The best way to do it is to add a generous whiskful of meringue into the almond-sugar batter and stir with a spatula like crazy until you don't see any white streaks and the batter looks more liquid. After that I added the rest of the meringue in 2-3 additions, stirring a lot at first and then slowing down towards the end until it is runny but not too much. You should then have trays of smooth and shiny unbaked macarons.

Tip #2: Control the Oven

Getting the batter right is only 50% of the whole process. You can throw all the effort down the drain if the cooking (i.e. oven) isn't controlled. In order for the macarons to have feet, they have to release steam during the cooking process. Ideally, they should be baked in an oven with the ventilation system open. However, most home ovens don't have ventilation and the only way to replicate this is to open the oven door during the cooking process. Otherwise, the macaron shells will crack.

The book suggested baking them at 180C for 12 minutes and opening the oven door twice, first at the 8th minute and second at the 10th. This is where you have to experiment with your own oven. For mine, I discovered that at 180C, 12 minutes was too long and opening the door twice wasn't enough. After 3.5 batches, the best batch (the one that didn't have any cracked shells and strong coloration) was the batch cooked for 10 minutes with the oven door opened 3 times and each time for 1 minute. I opened it for the whole of the 6th minute, 8th minute and 10th minute.

Yes, getting the hang of macarons is challenging and daunting at first. But once you've succeeded, the results can be rewarding. Not only will they be delicious, they're one of the quickest decadent desserts to make and one of the prettiest gifts for friends and family :)

Chocolate and Earl Grey Macarons

Adapted from Macaron by Pierre Herme

theoretically makes 48 macarons (96 shells)

Ingredients

For the shells:

200g almond powder

200g icing sugar

74g egg whites

2 tsp earl grey tea leaves

1 vanilla pod

8g cocoa powder

74g egg whites

50g water

150g caster sugar

For the ganache:

256ml whipping cream

16g earl grey tea leaves

266g milk chocolate, chopped

46g unsalted butter

Method

For the shells:

1. Grind the almond powder and icing sugar until very fine in a food processor (this is called a tant pour tant, TPT, in French)
2. Place them in a large bowl and add the earl grey tea leaves, cocoa powder and vanilla.
3. Mix the dry ingredients well with your hands, making sure to break the lumps.
4. Pour the first 74g of the egg white into the TPT and beat with a spatula until the mixture becomes wet and homogenous.
5. Scale the water and caster sugar into a small saucepan and the second 74g of egg whites in a medium bowl.
6. Cook the sugar to 118C, but start beating the egg whites on medium speed when the sugar is at 113C. You basically want the whites to be at soft peaks when the sugar is ready.
7. When the sugar reaches 118C, take it off the heat and pour it into the egg whites with the mixer still beating on low.
8. Once poured, increase the speed of the mixer and beat on high for 2 minutes. 
9. After that, lower the speed and beat until the meringue reaches 50C.
10. Incorporate the meringue into the TPT in several additions, beating well at first and slowing down towards the end to get the batter to magma consistency (see tip #1).
11. Pipe the shells on baking paper and leave them out to dry for 30 minutes or until the shells don't become dented when touched (As Jakarta is humid, it took me 40-45 minutes). 
12. Preheat oven to 180C while the shells are drying.
13. Bake for 9-12 minutes (see tip #2).
14. Once bake, immediately take the baking paper out of the try and leave the shells to cool on a wire rack.
15. Unmold only when they are cooled.

For the Ganache

1. Scale the cream in a saucepan and place the chopped chocolate in a medium bowl.
2. Once boiling, turn the heat off and add the tea leaves.
3. Stir and leave it to infuse for 5 minutes.
4. Strain the cream into another saucepan and bring it to boil again.
5. Once boiling, immediately pour over the chopped chocolate.
6. Whisk (in a concentric motion) to obtain a smooth ganache.
7. Place the ganache in the fridge until cool and thick like cream.

To finish

1. Using a piping bag, pipe a generous mound of ganache on a macaron shell
2. Cover with the other shell and rotate it to even out the filling.

The art of cake-assembly

French is such a strange but beautiful language. Sometimes, they say things in a straightforward manner that I find it alarming, especially after being used to their subtle English expressions. Other times, I just wonder at how they have a word for everything. Particularly in french pastry.


The French differentiates a bread bakery (boulangerie - person: boulanger) from a cake pastry shop (pâtisserie - person: pâtissier). They also set apart a chocolate shop (chocolaterie - person: chocolatier) and an ice cream parlor (glacerie - person: glacier). In pâtisserie, there is:


1. The making of the different types of cake bases: Biscuits - person: biscuitier
2. The assembly of the cakes: Petits Gateaux/Entremets - person: entremetier
3. The mending of the ovens: Four - person: fournier
4. The making of croissants, puff pastry and tart doughs: Tour - person: tournier

No one ever makes the entire product on a given day. Sure, you can be rotated between the stations, but on average each stay would at least be a few weeks long. During the internship, I've gone through chocolaterie/glacerie, tour, biscuits, petits gateaux and now, entremets. I guess the reason why they have so many stations is because each part of the cake requires a different set of skills. A person can be good at making croissants and rolling doughs (which needs A LOT of muscle strength) but not as detailed in assembling and decorating cakes. Or a person knowledgeable and skilled at making different cakes bases may not be as good as a judge in tempering, spreading and cutting chocolate decorations. The french pâtissiers want their product perfect (or close to it) and so weirdly enough, the assembly-line type of system works.

I'm scheduled to be in entremets for two weeks and after my first, it's hands down my favorite station of them all. In the morning, I decorate the large square or circular cakes and tarts. In the afternoon, I help prepare ganache and creams and assist my chef de partie (station leader) in assembling the cakes. There are so many components to assembling cakes and if you're not careful, so many things can go wrong. Excited with all the new things I've learnt and observed, I decided to practice them on an Opera at home. A green tea Opera.

So from my observations, here are a few tips:

1. For the joconde, it's good to heat the eggs and sugar over a bain-marie until it's warm to the touch. This gives the eggs and the overall cake more volume. For even more volume, the egg whites are beaten to stiff peaks with the sugar added in 3 additions: in the beginning, when they form soft peaks and towards the end. A failed joconde is a joconde that's dense and hard. I was quite happy that the joconde this time came out fluffy (not like the last one I made at school, haha)
2. For the buttercream, as it is half of the recipe from my old post, heat it over the bain-marie for 1.5 mins or so (it looks smooth like marshmallow cream quicker). Otherwise, you'll scramble them (which happened to my first batch :D ooops!).
3. For the ganache, make sure that the cream is boiling well (with big bubbles). Otherwise, the ganache will split. Stop whisking also once it looks smooth.
4. When using a metal spatula to smoothen the last layer of buttercream, it's easier to finish off with moving the spatula from the bottom part of the cake to the top (not from the sides, corners or top). Don't hesitate as this will create the bumps.
5. To unmold the cake, if you don't have a blow-torch, you can use a hair dryer. Put the cake on a cylinder-shaped item, set the hairdryer to the highest heat and heat the bottom half of the mold. Slide the ring from the sides. If the mold ring is not coming off, don't force it. Reheat again.

'Tis the season of the cherries

It's official. I now have a new favorite fruit.

I was always more of an apple or mandarin orange kind of girl. Those two fruits are practical. They are easy to store/handle (strawberries are super fragile! so I discovered this week at work), easy to eat (minimum soiling of hands/space from the juices, easy to dispose) and they have a pretty long fridge life (the strawberries I buy always go bad within a couple of days). Yeah, I'm not a strawberry fan unless they are already inside a dessert. Haha. But cherries.. Yum! Those I will more than tolerate.

Back in Indonesia, it was one of the most expensive fruits in the supermarket aisle. Here in France, they're everywhere and at such a great price! It's cherry season and has been since May. The price dropped from 10ish or so euros per kilo to, the cheapest I've seen today, four euros. The individual fruit also got bigger, shinier and not to mention sweeter. Hence, our mandarin orange supply at lunch has been switched to cherries.

So when I came across Pierre Herme's cherry and pistachio tart recipe from here, I just have to try it. I've also just gotten a few pastry supplies including tartelette pans and pistachio paste that are begging to be used. 

For these 5cm tartelettes, I baked them in a 180C oven for five minutes before adding the streusel topping. After that, they needed another 30 minutes. Compared to the recipe, this is a lot longer considering the size. Cooking times will vary according to what kind of oven you have. Mine is a miniature sized one so it's good to check the baking from time to time. Two good indicators are the topping and the bottom of the tart shell. The streusel topping and the bottom of your tart should turn golden brown. I finished off the tart with a dusting of icing sugar, a molded version of the previous white chocolate mousse and a cherry. Here is what it looks like inside~

Not exactly tiramisu

People have been asking whether this cake is a tiramisu. It could be...but I'd like to think not. The flavor combinations are similar but the cake came to be as an experiment on layering and on finding out whether coffee goes with spicebread.

Giving it another shot

It's been a while since I've made a cake 'with the works' at home - a layered buttercream cake or a layered mousse entremet. Last year, I made them week after week at school. These past few months, I was always tired after work and spent weekends going out. Plus, the tiny apartment's kitchen equipment and oven can't be compared to the professional's that I just thought it would be impossible to make anything worthwhile.


This week, I decided to give it another shot. Since I'll be moving to Petits Gateaux, I felt inspired and wanted to try something more elaborate than just cake bases at home. In French Pastry, a complex multilayered cake is called an entremet. It usually has one to two layers of cake and more layers of different creams, mousses and jellies. Sometimes, it has a tart base and most of the time, it's glazed. But it's always very rich in flavor and texture - in most pastry shops, it's made up of 4 to 5 different elements in one.


At school these were some of the entremets we made:

And they were considered the basics. So armed with the Pain d'epices, a bargain square cake ring and some pastry magazines and sites, I set to experiment. Here are pain d'epices entremets two ways (over 2 posts).

White Chocolate and Spicebread

with peach puree

Components

1. Pain d'epices
2. Peach puree (from here)
3. White chocolate mousse
4. Strawberry and speculoos crumbs

White Chocolate Mousse
adapted from So Good magazine, June 2009 edition


Ingredients
85ml milk
218ml whipping cream
200g white chocolate
3 gelatin sheets


Method

5. Pour the boiling milk over the chocolate. 
6. Whisk in the center until the chocolate turns to a smooth, elastic, glossy texture.
7. When the mixture is at 37C, pour over the whipped cream (If the chocolate mixture is less than 37C after being whisked, reheat it over a bain-marie.)

To Assemble: 

1. Cut the pain d'epices to the shape of the mold and place on the bottom.
2. Spread the peach puree immediately after it's cooked in the saucepan.
3. Freeze.
4. After the peach puree is firm, pour in the white chocolate mousse.
5. Freeze.

Things I will miss

Walking along the Pont Marie bridge and seeing the Notre-Dame from behind..

The hustle and bustle of people walking and queueing in the narrow streets of rue des Rosier and rue Veille du Temple..


The smell of melted butter and viennoisseries on the way to the metro at 5.30 every work day morning..


The aroma of honey, spice and tea from making pain d'epice..

This week marks the end of my stay at the Biscuit (cake production) station, which means that I have completed 4.5 out of 6 months of the internship. Last stop (up next) is Petits Gateaux, the assembly of individual-portioned cakes and tarts. I can't help but feel slightly sad. For the move at work but also for the foreshadow of leaving Paris soon. Like adapting to the lifestyle, I've grown to enjoy working in this station.


It wasn't always so. I remember not being able to sleep over my first few days at Biscuit. The station's notorious for requiring the fastest pace and accepting the least mistakes. Logically, it's sound. They have to make big batches of genoise, joconde, biscuit a cuilliere, choux or whatever cake type is required for the bi-weekly, weekly or daily stock of the shop. Every weekday morning, their sure task is to fill and glaze 20 or so eclairs (per flavor, we have two), several round choux and glaze a dozen trays of tarts with white or red glaze. On weekends, the number of eclairs spikes up to between 30-40 per flavor and there's the addition of a dozen or so bigger round choux for religieuse. This, of course, excludes the special orders of mini eclairs and round choux. "If you don't run throughout the day, you don't finish.." so my chef de partie likes to say. In practice, it's a lot to take on in the beginning for a fresh graduate. I remember my confusion of what goes where, what comes next, where is what and how do you tell when...I've also had some really bad days...like being sent to another station or messing things up one after another in front of the Head Chef in just one day.

You kind of get the hang of it after three weeks or so..Hahaha..and it's shortly after this time that I have to leave. Hence my reluctance. I've just learnt how to assemble the millefeuille, received fewer critiques on my pate a choux glazing and gotten the chance to fold/spread the genoise or make some whole cake recipes on my own (when required in a smaller scale). I want to practice them more. But well, I am grateful for the chance to at least see the processes. 


One of those cakes that I've made on my own before is the Pain d'Epice (french spice bread). Pain d'epice is not your typical american ginger bread. The spice can be anything that you want and the bread is usually denser. It's not very sweet and some places serve foie gras on slices of them. It makes a great afternoon tea cake.

The ingredients scaling of this cake at work is troublesome - a couple from the storage downstairs, a few from the Traiteur on the other side, the flour from the Boulangers downstairs on the other side and biscuits that I sometimes have to grind in the food processor first (it's supposed to be the job of another person, but the biscuits always run out of stock when he has a day off). To top it off, 80% of the time, the recipe falls short of the requirements - so begins the whole collection process again. Even so, I always look forward to making it. The mixture smells wonderful when the spice is added to the boiling honey, tea and milk and very well worth the trouble.

Luckily when you make it at home, you get the aroma and all the ingredients are within 2 sq meters (or so in my case). I didn't have the exact ingredients as at work and so changed the whole recipe. The cake came out lighter and tasted more nutty, something which I prefer. It tastes better after several hours.

Pain d'Epice
makes a 28cm x 22cm x 2.5cm cake


Ingredients
125ml milk
207g honey
Tea leaves from one bag of Twinnings orange-cinnamon tea (can be any tea you want)
40g sugar
5g baking soda
3g chilli powder
20g unsalted butter
125ml milk
50g chestnut spread
207g buckwheat flour (any wholemeal flour really)
5g baking powder
105g biscuits, ground to fine powder (I used speculoos but they can be anything; I've seen ice cream cones, eclairs, sponge fingers and even macaron shells being used)


Method

1. Preheat oven to 180C, butter and flour your mold.
2. Prepare your mise en place:
1. Whisk and sieve the flour, baking powder and biscuits into a medium bowl. 
2. Mix the sugar, baking soda and chilli powder in a small bowl.
3. Weigh your butter.
4. Put 125ml of milk and the chestnut spread in another small bowl.
3. Bring the other 125ml of milk, honey and tea leaves to a boil in a saucepan.
4. Sieve the mixture and bring it to a boil again.
5. When the mixture is bubbling and boiling, take off from the heat and whisk in the sugar-chilli mixture.
6. Whisk in the butter.
7. After the butter has fully melted, whisk in the milk and chestnut spread until fully incorporated.
8. Pour the hot liquid mixture over the dry ingredients in the bowl.
9. Incorporate the liquid into the flour in a slow folding motion but using a whisk. Stop as soon as all the flour has been incorporated. You don't want to overbeat the mixture/ whisk vigorously as this will make the cake tougher. 
10. Pour the batter into the mold and bake for 25 minutes or until a toothpick inserted to the center comes out clean.
11. Leave to cool for 10 minutes before unmolding and cooling the cake to room temperature on a rack.

Not just another tart

I didn't realize until the start of this post that I have been putting up tart recipes for the last few entries. Weird, lol. This will be another one, but before you dismiss it, hear me out. This is one recipe you do not want to miss. Plus, it isn't entirely a tart. You'll see what I mean.


One of the benefits of living in the Marais is easy access to great food. For french fare, there is Le dome du Marais or the modern-furnished Glou. For steaks, Robert & Louise serves them well-seasoned (with sea salt!) cooked over a flaming grill. If you're looking for more exotic flavors, Nanashi has an interesting reinvented gyudon (traditionally cooked beef over rice; Nanashi transformed it into a salad with lots of Arugula leaves and a light refreshing Japanese dressing) and L'as du Falafel has the best falafels worth queuing up to 20 minutes for. For something on the lighter side, there are several Jewish bakeries selling bagels, a few boulangeries with the standard baguette sandwiches, Candelaria for tacos or Tartes Kluger. True to its name, this cafe serves only tarts, both salty and sweet.


The tart which left an impression on me was their Chocolate Tart. It was the first time I had a moist brownie-like cake inside a tart shell. Although the chocolate was a tad bit too sweet I found the concept fascinating. What started as meaning to just have one bite ended up being the whole slice.  

Thus began my search for the chocolate filing to recreate the dessert at home. I wanted to keep the moist consistency but lessen the sweetness. The filling is definitely softer than an american style brownie and I'm pretty sure doesn't contain condensed milk like one recipe suggested. Being french-style, it's most likely a fondant cake and my favorite baker has one online recipe on it.


Her recipes in the past hadn't failed me. Neither did this one. It was beyond what I expected and if I may say, I preferred this filing to the original's. Not too sweet, very moist, kind of crumbly and really chocolatey. The recipe stands on its own without the tart base, so like I mentioned in the beginning, it's actually a brownie recipe. The best I've found thus far.


Strangely enough, I couldn't find the paddle attachment of my electric beater this morning. The recipe calls for the eggs and sugar to be beaten for 2 minutes with the electric beater. But seeing how they make genoise in the pastry kitchen of my internship got me thinking of an idea. The recipe below has been modified to be entirely hand-made :D


French Brownie Tart
adapted from here
makes a 20cm tart


Ingredients
220g sweet shortcrust pastry (pate sucree)
85g bittersweet chocolate (70% Lindt)
50g unsalted butter, cut into pieces
35g salted butter (or 85g unsalted butter and a pinch of salt)
2 eggs
1/2 cup caster sugar
1/4 cup all-purpose flour
a pinch of cinnamon
chocolate chips, for garnish (optional)


Method

1. Preheat oven to 180C.
2. Line a tart ring/mold and blind-bake the shell for 15-20 minutes or until light golden brown
3. Meanwhile, melt the chocolate in a bowl over a bain mairie (a saucepan of simmering water).
4. Take off the bowl, add the butter into the chocolate and mix until the butter is fully melted. If there are pieces that are not melting, put it over the water again. Ensure that the mixture doesn't get too hot. Set aside.
5. In a medium bowl, crack the two eggs and whisk until the yolks and whites are mixed well (important to ensure the sugar is incorporated properly in the next step).
6. Add half of the sugar and whisk immediately.
7. Set the bowl over a bain mairie, whisking all the while, until the egg mixture is hot to the touch (when the eggs are tempered).
8. Once the eggs are tempered, take the bowl out of the bain mairie, add the rest of the sugar and continue whisking until the mixture is thick and pale (almost white).
9. Pour in the melted chocolate-butter mixture and mix only until it is incorporated.
10. Fold in the flour and cinnamon powder.
11. Scrape the batter into the tart shell, top with the chocolate chips if using, and bake for 25-30 minutes, or until a knife inserted to the center comes out clean.
12. Leave the tart to cool in the mold/ring for several minutes before unmolding and transferring it to a rack to cool to room temperature.
13. Slice and serve :)
