½ punnet strawberries, washed and green part removed
½ punnet raspberries, washed

Place saucepan half filled with water onto the stove and bring to a simmer.
Combine egg yolks and sugar in a heatproof bowl, sit the bowl on top of the saucepan and whisk until fluffy.
Add 1/3 cup Marsala wine, continue to whisk until the mixture forms a ribbon (about ten minutes).
Remove the bowl, and set aside to cool.
Gently fold the mascarpone into the cooled egg mixture.
In a separate bowl, whisk the egg whites into soft peaks and gently fold through the egg and mascarpone mixture.
Place coffee and remaining Marsala into a bowl. Briefly dip the biscuits into the coffee mix and lay them into a trifle dish, then layer with the mascarpone mix. Top with another layer of soaked biscuit and so on, finishing with a layer of mascarpone mix.
Refrigerate for at least two hours, or overnight.
Before serving, dust with cocoa powder and garnish with fresh berries.
