Lime mousse cake with prickly pear gelee

Where have I been? Well, life gets very busy and I have found for my sanity I need to take a step back and focus on family and work first. But that doesn't mean I don't love to bake, and Daring Baker's challenges are a great way to do this. This month sounds like a big deal, but it is a lot easier than it looks. I was inspired by a recent find of Prickly Pear puree, so here is my contribution. Lime mousse cake with prickly pear gelee. if you have never had prickly pear, it is a wonderful delicate floral flavor.

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.

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.)
8. Cut in strips and place into mousse cake rings lined with acetate or parchment paper.
