Daring Baker's January Challenge: Entremet

The January 2011 Daring Bakers’ challenge was hosted by Astheroshe of the blog accro. She chose to challenge everyone to make a Biscuit Joconde Imprime to wrap around an Entremets dessert.

I made a Coffee Mousse Entremet with a chocolate glaze.

Here's how:

COCOA Décor Paste Variation: Reduce cake flour to 6 oz / 170g. Add 2 oz/ 60 g cocoa powder. Sift the flour and cocoa powder together before adding to creamed mixture.

Directions:

1. Cream butter and sugar until light and fluffy (use stand mixer with blade, hand held mixer, or by hand)
2. Gradually add egg whites. Beat continuously.
3. Fold in sifted flour.
4. Tint batter with coloring to desired color, if not making cocoa variation.

Preparing the Joconde- How to make the pattern:

1. Spread a thin even layer of décor paste approximately 1/4 inch (5 millimeter) thick onto silicone baking mat with a spatula, or flat knife. Place mat on an upside down baking sheet. The upside down sheet makes spreading easier with no lip from the pan.
2. Pipe or Pattern the décor paste – Here is where you can be creative. Make horizontal /vertical lines (you can use a knife, spatula, cake/pastry comb). Squiggles with your fingers, zig zags, wood grains. Be creative whatever you have at home to make a design can be used. OR use a piping bag. Pipe letters, or polka dots, or a piped design. If you do not have a piping bag. Fill a ziplock bag and snip off corner for a homemade version of one.
3. Freeze until hard

 

Joconde Sponge

YIELD: Two ½ size sheet pans or a 13” x 18” (33 x 46 cm) jelly roll pan
Ingredients:
¾ cup/ 180 ml/ 3oz/ 85g almond flour/meal - *You can also use hazelnut flour, just omit the butter
½ cup plus 2 tablespoons/ 150 ml/ 2⅔ oz/ 75g confectioners' (icing) sugar
¼ cup/ 60 ml/ 1 oz/ 25g cake flour *See note below
3 large eggs - about 5⅓ oz/ 150g
3 large egg whites - about 3 oz/ 90g
2½ teaspoons/ 12½ ml/ ⅓ oz/ 10g white granulated sugar or superfine (caster) sugar
2 tablespoons/ 30 ml/ 1oz / 30g unsalted butter, melted
*Note: How to make cake flour: http://www.joythebaker.com/blog/2009/09/how-to-make-cake-flour/
Directions:

1. In a clean mixing bowl whip the egg whites and white granulated sugar to firm, glossy peeks. Reserve in a separate clean bowl to use later.
2. Sift almond flour, confectioner’s sugar, cake flour. (This can be done into your dirty egg white bowl)
3. On medium speed, add the eggs a little at a time. Mix well after each addition. Mix until smooth and light. (If using a stand mixer use blade attachment. If hand held a whisk attachment is fine, or by hand. )

 Fold in one third reserved whipped egg whites to almond mixture to lighten the batter. Fold in remaining whipped egg whites. Do not over mix.

Spread the Jaconde batter over the frozen decor paste.

Bake in 350 degree oven until cooked through.

Line a mould with plastic wrap and put parchment paper around the sides. Then cut the sponge to measure so it fits snuggly in the cake pan. Freeze the sponge while prepping the mousse.

Coffee Mousse

5 oz brewed coffee

5 oz sugar

5 yolks

2 gelatin sheets

12 fl oz heavy cream

Make a sabayon by heating the first three ingredients over a bain marie. Stir constantly until the mixture feels hot to the touch. Then put in a stand mixer and whisk until cold.

Whip the cream and hydrate the gelatin. Squeeze the water out of the gelatin and heat it up till melted. Fold into the sabayon, then fold in whipped cream. Pour the mousse into the sponge. If you want you can add a second cake layer down the middle, just like in the photo below. Then top with more mousse. 

Freeze until set, then make a ganache and drizzle over the mousse. (Heat up 1 part cream to 1.5 parts chocolate.)

Freeze until set. Then you can unmould and decorate the top as desired.

 

Enjoy!!
