Pour gelatin with water and leave to swell.
Wash the fruits, peel and chop them. Cut the biscuit into small pieces.
Mix sour cream with sugar and whisk with a mixer.
We heat up the swollen gelatin in a water bath without boiling. And pour into sour cream, stir.
Cover the deep dishes with cling film. Pour some berries on the bottom. Lay pieces of biscuit on top. Pour cream.
And then lay in layers. On top, cover with a film and send it to the refrigerator. Three hours later, the cake is ready.
