Chocolate and cherry teardrops

Method

1. Place 80g of the chocolate in a bowl set over a pan of simmering water, and melt gently. Cut the acetate into 6 x 30cm x 5cm strips, and with a sharp knife cut 6 teardrop shapes (about 1.5cm thick) out of the chocolate sponge (large enough for the acetate to wrap around). Brush 1 side of each strip thickly with the chocolate. Shape around the sponge teardrops (with the chocolate on the inside); secure with a paperclip. Leave to set in the fridge.
2. Whisk the egg yolks and sugar until thick and pale. Melt the butter with the cocoa and remaining chocolate in a bowl set over a pan of simmering water, stirring occasionally. Fold the melted chocolate mixture into the egg mixture. Lightly whisk the cream in a bowl, then fold it into the chocolate mixture to make a mousse.
3. Spoon a layer of cherries into the teardrops (on top of the sponge) and pipe or spoon the mousse on top. Chill for 1 hour, then carefully unpeel the acetate from the teardrops. Decorate with more cherries and dust with the silver leaf.
