We slice the curd into thin pieces and lightly moisten it with a salted mixture of beaten eggs and milk. Rinsed apples are peeled, cored and diced. We grease a enameled GN 1/3 with butter and spread a third of the moistened breadcrumbs on the bottom. We layer half of the apple portion on the breadcrumbs, sprinkle with raisins and half of the granulated sugar mixed with cinnamon. We spread half of the portion of quark flavored with powdered sugar on top and layer it with the next 1/3 of the moistened breadcrumbs. We add another layer of apples and quark, and the last layer will be the remainder of the moistened breadcrumbs. On the surface, we drizzle the remaining portion of melted butter. We bake the curd as instructed, after the sound signal we brush with whipped egg white mixed with a little powdered sugar and bake until the top turns golden. We slice and serve sprinkled with powdered sugar and vanilla sugar.
