Chocolate Orange Trifle

Directions

1. 1
   Break up the trifle sponges and place in a large glass serving bowl. Sprinkle the crumbled macaroons on top, then sprinkle the sherry.
2. 2
   Squeeze the juice from two mandarins and sprinkle it over the macaroons. Peel and segment 6 mandarins and arrange them in the dish.
3. 3
   In a large bowl, combine egg yolks, sugar, and cornstarch to make a paste. Bring the milk to just below boiling in a small pan. Remove and pour it into the egg yolk mixture.
4. 4
   Return the custard to a clean pan and cook over low heat, stirring constantly to avoid curdling.
5. 5
   When custard is thick, return it to the bowl, then stir in the mascarpone and melted chocolate until thoroughly combined. Spread the custard evenly over the trifle and chill for 1 hour.
6. 6
   Whip the cream until thick, then spread over the top of the trifle. Decorate with marbled chocolate shapes and remaining mandarin orange segments.
