Separate the whites from the yolks. Beat the yolks with sugar.
Mix the starch and flour in a separate bowl and add to the yolks.
In a separate bowl, beat the egg whites until stiff. Carefully add the proteins to the bulk and mix gently (just mix so that the proteins do not settle).
Transfer the dough to a baking dish and place in the oven. Bake at 180 degrees for about 15-20 minutes.
Take out the biscuit, cool and cut into 2 cakes (one cake should be thinner, it will go to the base of the cake).
Cut canned apricots and pineapples into small cubes (set aside some of the fruit for decoration – 3 slices of pineapple and apricot).
Grease a large salad bowl with vegetable oil and line it with cling film.
Arrange the bottom and sides of the salad bowl with apricots and pineapples.
Cool the cream. Whip the cooled cream with powdered sugar until a thick, non-spreading foam is formed.
Soak gelatin in water, following the instructions on the package.
Put the yogurt into a bowl and add the strained gelatin solution, stirring occasionally. Mix everything well.
Combine the yogurt-gelatin solution with the whipped cream and mix well until smooth.
Cut the larger crust into cubes and mix with the chopped fruit.
Pour some cream into a salad bowl and spread so that it covers the bottom. Top with a piece of sliced sponge cake with fruit.
Put another layer of cream, then again a biscuit with fruit. So repeat until filling.
Put the cake on top and put the cake in the refrigerator overnight.
Turn the salad bowl over. Take out the cake and decorate with grated chocolate on top.
