Put 200g of the raspberries in a small saucepan with the icing sugar and one tablespoon of whisky liqueur. Reserve the remaining raspberries to garnish.
Heat gently till the raspberries start to go squidgy and all the icing sugar is dissolved.
Put in the fridge to chill.
Whip the fresh cream till it forms stiff peaks
Beat the egg yolks and one tablespoon of whisky liqueur into the marscapone.
Now fold the mascapone mixture gently into the fresh cream
Take the sponge fingers and break up into the remaining whisky liqueur
Spread the sponge finger mixture over the base of a pretty serving dish. You'll need something around 15cm square by 3cm deep
Now add the raspberry mixture in one layer
Top with the mascarpone cream mixture
Put in the fridge and leave to chill for at least 2 hours.
Just before serving, top the raspberry tiramisu with chocolate crunch and stud with raspberries and sprigs of fresh mint
