Baileys tiramisu trifle

Method

• step 1

  To make the custard, put the whole milk in a large pan over a medium heat and bring to a simmer. Meanwhile, put the cornflour, caster sugar, vanilla and eggs into a large bowl and whisk until smooth. Pour the hot milk over the egg mixture, whisking together. Pour the custard back into the pan and cook gently, whisking constantly, until thickened. Divide the custard equally between 2 bowls. To one, add the 50g chopped dark chocolate and sea salt, whisking until the chocolate has melted. To the second, add the mascarpone and Baileys, whisking until evenly combined. Press a sheet of clingfilm onto the surface of the custards to stop skins forming and chill for a few hours.

• step 2

  When ready to assemble, slice the swiss roll into 2cm-thick slices. Mix the hot coffee and the amaretto. Quickly dip one side of the slices of swiss roll into the coffee mixture and use to line the sides of a trifle bowl. Take the remaining slices and break into pieces, filling the bottom of the bowl. Drizzle over the remaining coffee mixture. Spread the Baileys custard over the base, followed by a layer of crushed amaretti biscuits and then the chocolate custard. Chill for a few hours or overnight.

• step 3

  When ready to serve, put the brown sugar and espresso powder into a small bowl and pour over 2 tbsp boiling water, mixing to combine. Pour this coffee mixture into the double cream and whisk until it just holds soft peaks. Dollop the cream onto the trifle and top with the shaved chocolate.

• step 4

  Once fully assembled the trifle will keep for a day in the fridge but you can make the custard bases a few days ahead and chill until ready to assemble.
