A cross between a trifle and tiramisu, this really is simple to do. Roast apricots with orange, then layer up with mascarpone and custard for an indulgent dessert
Heat oven to 220C/fan 200C/gas 7. Tip the apricots into a roasting tin, toss with the orange zest, juice and sugar and roast for 15-20 mins until soft. Remove the skins if you like. Tip into a bowl to cool.
Whisk the mascarpone and custard together until completely blended.
Tip the biscuits into a large glass bowl, then top with the apricots and custard. Scatter generously with the grated chocolate, then cover and chill until ready to serve.
