1. Reserve 3 raspberries per person in the fridge.
If you have bought frozen raspberries: Thaw the rest in the microwave (without cooking them!) or in the fridge if you have time, then
Blend them to obtain a coulis. (if the fruits are not sweet enough, adjust to your taste)
2. Pour the mascarpone into a small bowl, add the heavy cream and powdered sugar.
3. Whisk with an electric mixer, starting slowly and gradually increasing the speed until the cream holds its shape and forms peaks.
4. Add three-quarters of the raspberry coulis to the cream. Gently mix the cream and coulis to create a marbled effect.
5. Roughly crush the biscuits and distribute half of the crumbs in the bottom of each glass.
6. In each glass, add 1 raspberry, 1 tablespoon of coulis, and 2 tablespoons of cream.
Repeat 2 more times.
7. Finish with the remaining biscuit crumbs and serve immediately so that the biscuits stay crunchy.
