Some desserts look impressive but turn out to be ordinary after the first spoonful. Others surprise you from the very first layer. This dessert belongs firmly in the second category. It combines intensely fruity kisiel, a Polish fruit pudding made here with strawberries and sour cherries, delicate mascarpone cream, a light mousse made from jelly and milk, and irregular pieces of jelly on top. The result looks a little like a dessert from a patisserie, yet you can easily make it at home without baking or complicated ingredients.
