Daring Bakers: Biscuit Joconde Imprime with Apple, Lemon and White Chocolate-Rosemary Entremets


This month for the Daring Bakers we made a special french dessert. It is called a Biscuit Joconde Imprime Entremets. When I was first reading it I had no idea what it is, but a look at the pictures clarified it. I always admired these kind of desserts and wanted to make it for a long time. It makes a great presentation for a cake, and looks very elegant. I will definitely make them again, since you can get really creative with the flavor combination.

A Biscuit Joconde is a kind of sponge cake which is flexible and can be wrapped around a cake. The impreme means that a pattern is printed on the biscuit. This is done buy using a different color of dough first, letting it cool, and then apply the Joconde dough, before baking. An Entremet is a cake which consists of several layers. This is where the Joconde is wrapped around.

My Entremet consisted of the following layers: First a layer of sauteed apples cooked in wine and calvados, spiced with some vanilla, which was then thickened with corn starch. Next I added a layer of lemon curd. After cooling I made a layer of White Chocolate Mousse with a hint of Rosemary, which matched good with the apples. The top layer was a glaze of mango puree, which gave a beautiful color.

Unfortunately my Biscuit Joconde got a little dark. It is very important to closely watch it in the oven, as it browns very fast. The recipe makes a whole big sheet, so you can freeze some for another cake.

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.


Joconde Sponge

YIELD: Two ½ size sheet pans or a 13” x 18” (33 x 46 cm) jelly roll pan

Ingredients:
85g almond flour/meal - *You can also use hazelnut flour, just omit the butter
75g confectioners' (icing) sugar
25g cake flour
3 large eggs
3 large egg whites
2½ tsp. sugar or superfine (caster) sugar
30g butter, melted

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. )
  4. 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.
  5. Fold in melted butter.
  6. Reserve batter to be used later.

Patterned Joconde-Décor Paste

YIELD: Two ½ size sheet pans or a 13” x 18” (33 x 46 cm) jelly roll pan

Ingredients
200g unsalted butter, softened
200g Confectioners' (icing) sugar
7 large egg whites
220g cake flour
Food coloring gel, paste or liquid
COCOA Décor Paste Variation: Reduce cake flour to 170g. Add 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. 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. Slide the baking sheet with paste into the freezer. Freeze hard. Approx 15 minutes.
  4. Remove from freezer. Quickly pour the Joconde batter over the design. Spread evenly to completely cover the pattern of the Décor paste.
  5. Bake at 475ºF /250ºC until the joconde bounces back when slightly pressed, approx. 15 minutes. You can bake it as is on the upside down pan. Yes, it is a very quick bake, so watch carefully.
  6. Cool. Do not leave too long, or you will have difficulty removing it from mat.
  7. Flip cooled cake on to a powdered sugared parchment paper. Remove silpat. Cake should be right side up, and pattern showing! (The powdered sugar helps the cake from sticking when cutting.)
Preparing the MOLD for entremets:
You can use any type of mold. I would suggest:
  1. Start with a large piece of parchment paper laid on a very flat baking sheet. Then a large piece of cling wrap over the parchment paper. Place a spring form pan ring, with the base removed, over the cling wrap and pull the cling wrap tightly up on the outside of the mold. Line the inside of the ring with a curled piece of parchment paper overlapping top edge by ½ inch. CUT the parchment paper to the TOP OF THE MOLD. It will be easier to smooth the top of the cake.
  2. A biscuit cutter/ cookie cutter- using cling wrap pulled tightly as the base and the cling covering the outside of the mold, placed on a parchment lined very flat baking sheet. Line the inside with a curled piece of parchment paper overlapping.
  3. Cut PVC pipe from your local hardware store. Very cheap! These can be cut into any height you wish to make a mold. 2 to 3 inches is good. My store will cut them for me, ask an employee at your store. You can get several for matching individual desserts. Cling wrap and parchment line, as outlined above.
  4. Glass Trifle bowl. You will not have a free standing dessert, but you will have a nice pattern to see your joconde for this layered dessert.
Preparing the Jaconde for Molding:
  1. Trim the cake of any dark crispy edges. You should have a nice rectangle shape.
  2. Decide how thick you want your “Joconde wrapper”. Traditionally, it is ½ the height of your mold. This is done so more layers of the plated dessert can be shown. However, you can make it the full height.
  3. Once your height is measured, then you can cut the cake into equal strips, of height and length. (Use a very sharp paring knife and ruler.)
  4. Make sure your strips are cut cleanly and ends are cut perfectly straight. Press the cake strips inside of the mold, decorative side facing out. Once wrapped inside the mold, overlap your ends slightly. You want your Joconde to fit very tightly pressed up to the sides of the mold. Then gently push and press the ends to meet together to make a seamless cake. The cake is very flexible so you can push it into place. You can use more than one piece to “wrap “your mold, if one cut piece is not long enough.
  5. The mold is done, and ready to fill.
*Note: If not ready to use. Lay cake kept whole or already cut into strips, on a flat surface, wrap in parchment and several layers of cling wrap and freeze.

Entremet- Filling Options:
It is nice to have a completed dessert so you can unmold and see the Joconde working. Fill with anything you desire. Layers of different flavors and textures! However, it needs to be something cold that will not fall apart when unmolded.

Suggestions:
Mousses, pastry creams, Bavarian creams, cheesecakes, puddings, curds, jams, cookie bases, more cake (bake off the remaining sponge and cut to layer inside), nuts, Dacquoise, fresh fruit, chocolates, gelee.
