Ingredients
Method
Combine frozen berries and 2 cups water in a large saucepan over high heat. Bring to a boil. Remove from heat. Stir in jelly, one packet at a time, until dissolved. Transfer to a large heatproof bowl. Cool slightly, then refrigerate for 2 to 3 hours, until thickened and starting to set.
Arrange the cake over the base of a glass trifle dish (12-14 cup capacity). Spoon over the jelly mixture. Cover. Refrigerate for about 2 hours, or until set.
Beat custard and one tub of mascarpone in a small bowl of an electric mixer until soft peaks form. Don’t overbeat. Spoon over the jelly layer. Smooth over top. Cover and refrigerate until ready to serve.
Just before serving, whisk the remaining mascarpone in a medium bowl with 1 tblsp water until smooth. Spoon over custard later. Decorate with fresh berries and flaked almonds (optional).
