Kolomna Pastila (Fluffy). Recipe from Chef Maxim Grigoryev
Pastila can be made from a wide variety of fruits, even berries. If using berries, they are first washed, the pulp is pressed through a sieve, mixed with sugar, syrup, or honey, and then whipped until foamy. If using honey, whip it until it turns white. To ensure the pastila is sufficiently fluffy, it must be whipped continuously.
