Instructions

Step 1

Melt the Butter and Chocolate: Melt the butter with the chocolate, and then set aside.
You can use a double boiler or microwave for ease.

Step 2

Add Sugar and Eggs: Add the sugar and eggs, mixing well.
Continue mixing until the sugar is fully dissolved.

Step 3

Bake: Bake the dough in two 14cm (5.51 inch) rings at 338°F (170°C) for about 10-12 minutes.
Use a toothpick to check for doneness; it should come out clean when inserted into the center.

Step 4

Note: The calculation in the recipe is for a 16cm (6.30 inch) cake.

Step 5

Prepare Gelatin: Soak the gelatin in cold water.
Ensure the gelatin is fully submerged.

Step 6

Mix Ingredients for Confit: Add sugar and starch to the blueberry puree, and mix well.
Stir constantly to avoid lumping.

Step 7

Cook Confit: Put the puree mixture over low heat, and bring it to a boil. Then boil for 1 minute. Cool it for 2-3 minutes, and then add the gelatin.
Stir thoroughly to mix the gelatin evenly.

Step 8

Prepare Mold: Wrap a 14cm (5.51 inch) ring with film on the bottom.
Use a tight seal to prevent leakage.

Step 9

Assemble Confit Layer: Lay out a biscuit, pour out the confit, and cover with a second biscuit on top.
Ensure an even layer of confit for best results.

Step 10

Freeze Confit Layer: Put the assembled biscuit and confit in the freezer for 1 hour.

Step 11

Prepare Gelatin for Mousse: Soak the gelatin in cold water.
Similar to confit gelatin preparation.

Step 12

Heat Chocolate and Puree: Heat the white chocolate and blueberry puree until the chocolate melts. Mix well.
Stir constantly to avoid burning the chocolate.

Step 13

Add Gelatin to Mousse: Add the dissolved gelatin to the mixture.

Step 14

Prepare Whipped Cream: Whip the cold cream to soft peaks.
Chill the bowl and whisk for faster whipping.

Step 15

Combine Cream and Chocolate Mixture: Mix part of the whipped cream into the chocolate mass, then add the rest of the cream. Mix thoroughly with a silicone spatula.

Step 16

Prepare Final Assembly: Wrap a 16cm (6.30 inch) ring with foil.
Ensure no gaps to prevent leaks.

Step 17

Assemble Entire Cake: Put the biscuits with confit on the bottom, and pour the mousse on top. Pour part of the mousse into a "heart" mold.
