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.
A joconde imprime is the outside cake wrapper of the Entremets dessert. (See photo below – the striped cake at the bottom of this dessert is the Joconde imprime)
Joconde imprime /entremets. A joconde imprime (French Baking term) is a decorative design baked into a light sponge cake providing an elegant finish to desserts/torts/entremets/ formed in ring molds. A joconde batter is used because it bakes into a moist, flexible cake. The cake batter may be tinted or marbleized for a further decorative effect.
This Joconde/spongecake requires attentive baking so that it remains flexible to easily conform to the molds. If under baked it will stick to the baking mat. It over baked it will dry out and crack. Once cooled, the sponge may be cut into strips to line any shape ring mold.
Entremets (French baking term)- an ornate dessert with many different layers of cake and pastry creams in a mold, usually served cold. Think Trifle in a mold vs. a glass bowl.
The above-mentioned information and photo came from The Daring Kitchen website.
I colored my cake a dark purple, which only got darker, almost black, when baked. I recommend using a light/bright color. Or the chocolate version would be cool. I filled my cake with two mousses, one dark chocolate, and one white chocolate. I got the recipes for the mousses from the cookbook Baking, by James Peterson.
