August Daring Bakers' Challenge--Eclairs with Coffee Pastry Cream

It's time for another Daring Bakers' Challenge posting. I was very excited when I found out that August's challenge would be a recipe from Pierre Herme. I followed the recipe to the letter , but I was taken aback when my pate a choux dough was too runny. I've worked with other pate a choux recipes before and they weren't as runny as this one. I baked the first batch, but they came out deflated. So I decided to add more flour to my batter to make it more stable. I was happy with the results of the second batch. I also made a coffee pastry creme rather than chocolate. The result was heavenly! Thank you to Meeta K and Tony for this month's challenge



Pierre Hermé’s Cream Puff Dough

Recipe from Chocolate Desserts by Pierre Hermé(makes 20-24 Éclairs)

• ½ cup (125g) whole milk

• ½ cup (125g) water

• 1 stick (4 ounces; 115g) unsalted butter, cut into 8 pieces

• ¼ teaspoon sugar

• ¼ teaspoon salt

• 1 cup (140g) all-purpose flour

• 5 large eggs, at room temperature

1) In a heavy bottomed medium saucepan, bring the milk, water, butter, sugar and salt to theboil.

2) Once the mixture is at a rolling boil, add all of the flour at once, reduce the heat to mediumand start to stir the mixture vigorously with a wooden spoon. The dough comes together veryquickly. Do not worry if a slight crust forms at the bottom of the pan, it’s supposed to. Youneed to carry on stirring for a further 2-3 minutes to dry the dough. After this time the doughwill be very soft and smooth.

3) Transfer the dough into a bowl of a mixer fitted with the paddle attachment, or using yourhandmixer or if you still have the energy, continue by hand. Add the eggs one at a time,beating after each egg has been added to incorporate it into the dough.You will notice that after you have added the first egg, the dough will separate, once again donot worry. As you keep working the dough, it will come back all together again by the time youhave added the third egg. In the end the dough should be thick and shiny and when lifted itshould fall back into the bowl in a ribbon.

4) The dough should be still warm. It is now ready to be used for the éclairs as directed above.

Notes:1) Once the dough is made you need to shape it immediately.

2) You can pipe the dough and the freeze it. Simply pipe the dough onto parchment-lined bakingsheets and slide the sheets into the freezer. Once the dough is completely frozen, transfer thepiped shapes into freezer bags. They can be kept in the freezer for up to a month.



Chocolate Pastry Cream Recipe

from Chocolate Desserts by PierreHermé

• 2 cups (500g) whole milk

• 4 large egg yolks

• 6 tbsp (75g) sugar

• 3 tablespoons cornstarch, sifted

• 1 teaspoon instant coffee

• 2½ tbsp (1¼ oz: 40g) unsalted butter, at room temperature

1) In a small saucepan, bring the milk to a boil. In the meantime, combine the yolks, sugar and cornstarch together and whisk in a heavy‐bottomed saucepan.

2) Once the milk has reached a boil, temper the yolks by whisking a couple spoonfuls of the hot milk into the yolk mixture.Continue whisking and slowly pour the rest of the milk into the tempered yolk mixture.

3) Strain the mixture back into the saucepan to remove any egg that may have scrambled. Place the pan over medium heat and whisk vigorously (without stop) until the mixture returns to a boil. Keep whisking vigorously for 1 to 2 more minutes (still over medium heat).Stir in the melted chocolate and then remove the pan from the heat.

4) Scrape the pastry cream into a small bowl and set it in an ice‐water bath to stop the cooking process. Make sure to continue stirring the mixture at this point so that it remains smooth.

5) Once the cream has reached a temperature of 140 F remove from the ice‐water bath and stir in the butter in three or four installments. Return the cream to the ice‐water bath to continue cooling, stirring occasionally, until it has completely cooled. The cream is now ready to use or store in the fridge.

Notes:

1) The pastry cream can be made 2‐3 days in advance and stored in the refrigerator.

2) In order to avoid a skin forming on the pastry cream, cover with plastic wrap pressed onto the cream.

3) Tempering the eggs raises the temperature of the eggs slowly so that they do not scramble.



Chocolate Glaze

Recipe from Chocolate Desserts by Pierre Hermé(makes 1 cup or 300g)

• 1/3 cup (80g) heavy cream

• 3½ oz (100g) bittersweet chocolate, finely chopped

• 4 tsp (20 g) unsalted butter, cut into 4 pieces, at room temperature

• 7 tbsp (110 g) Chocolate Sauce (recipe below), warm or at room temperature

1)In a small saucepan, bring the heavy cream to a boil. Remove from the heat and slowly begin to add the chocolate, stirring with a wooden spoon or spatula.

2) Stirring gently, stir in the butter, piece by piece followed by the chocolate sauce.

Notes: 1) If the chocolate glaze is too cool (i.e. not liquid enough) you may heat it briefly
 in the microwave or over a double boiler. A double boiler is basically a bowl sitting over (not touching) simmering water.

2) It is best to glaze the eclairs after the glaze is made, but if you are pressed for time, you can make the glaze a couple days ahead of time, store it in the fridge and bring it up to the proper temperature (95 to 104 F) when ready to glaze.



Chocolate SauceRecipe

from Chocolate Desserts by Pierre Hermé (makes 1½ cups or 525 g)

• 4½ oz (130 g) bittersweet chocolate, finely chopped

• 1 cup (250 g) water

• ½ cup (125 g) crème fraîche, or heavy cream

• 1/3 cup (70 g) sugar

1) Place all the ingredients into a heavy‐bottomed saucepan and bring to a boil, making sure to stir constantly. Then reduce the heat to low and continue stirring with a wooden spoon until the sauce thickens.

2) It may take 10‐15 minutes for the sauce to thicken, but you will know when it is done when it coats the back of your spoon.

Notes: 1) You can make this sauce ahead of time and store it in the refrigerator for two weeks. Reheat the sauce in a microwave oven or a double boiler before using.2) This sauce is also great for cakes, ice-cream and tarts.
