Apple foam

Bake the apples, cut out the core from them and wipe through a sieve. Add the sugar, protein and whisk together, dropping the bowl of mass into the cold water. When the mass thickens so that the spoon in it will stand vertically, gain mass with a spoon and lay out on a baking sheet lined with oil-lubricated paper. Put in a warm oven (150 ° C) so that the foam does not bake, but dries.
