Soak the gelatin in a bowl of cold water.
Mix 800 g of washed and hulled strawberries with the sour and the juice of 1/2 lemon. Warm 2 spoonfuls of this coulis in a saucepan, whisk in the drained gelatin over low heat. When it is dissolved, incorporate half of the strawberry coulis (and keep the other half in the fridge in an airtight box for decoration), the whipped cream in firm whipped cream and finally the last strawberries cut into pieces.
Butter the bottom and sides of a charlotte mold then line with stretch film. Fill it with the strawberry mousse, place at least four hours in the fridge.
Carefully unmold the charlotte and remove the stretch film. Cover the top and the edges with the Russian cigarettes tightly pressing lightly to make them adhere.
Gently coat with a few spoonfuls of strawberry coulis by dripping it between the biscuits, serve the rest in a sauce boat.
