Grease the sides of souffle dishes with some butter.
Now, wrap a silicon paper around the upper part of the dish (or cup) and secure it with a tape.
This is to allow the souffle to go over the dish. (for an authentic souffle effect!)
Pour the strawberry souffle mixture into the souffle dishes, filling it up until it reaches the top of the paper. (for a better idea, observe the shape of the souffle in the picture) freeze overnight.
To serve, remove the silicon paper, then remove from the mold.
Arrange on dessert plates and garnish with strawberries (optional).
