Heat the rest of the fruits in a little saucepan until you get a kind of coulis. Sieve and reserve.
Mix mascarpone and cottage cheese with sugar.
Place first in your individual glasses crumbled biscuits (reserve a bit to decorate) and half of cottage cheese mix. Cover with red berry coulis. Add the rest of cottage cheese mix and cover with the rest of the coulis, fresh red berries and crumbled biscuits.
