It sounds yummy none the less
Actually the Germans have adapted many non German recipes meanwhile.
Besides that, there are other recipes with apples which are not necessarily desserts. heaven and Earth, e.g., one of my favourite recipes. "Himmel und Erde" in German.
It's one of the typical regional dishes here, made of potatoes and apples. My MIL makes it this way:
Equal amount of each potatoes and apples, a bit sugar and lemon juice, bacon grease, onion to taste, salt, pepper.
Boil the potatoes in salted water, then lightly mash, so that there are still lumps. Season with some pepper to taste. In a saucepan, combine peeled, cored and sliced apples with some sugar and lemon juice, saute, then lightly mash, too, and mix with the potatoes, keep warm in the oven.
In the bacon grease, fry the sliced onions until nicely browned.
Divide potato and apple mixture onto plates, garnish with the onions and some of the bacon grease poured over, serve with sausages, blood sausage or meatballs or German meatloaf.
