Separate the egg yolks from the egg white. Prepare the fruit: e.g. peel, core, eighth and cut the apples into thin slices or sort the berries.
Mix the egg yolks with sugar, vanilla sugar, flour, milk and salt to form a smooth dough. Beat the egg whites until stiff. First stir the fruit into the batter, then carefully fold in the egg whites.
Melt the fat in a pan and bake thick pancakes in it over low to medium heat until golden brown. Put the pancakes on a plate and sprinkle with sugar.
Makes about 12 pancakes.
Tip: Don`t bake the pancakes too long. They taste best when they are still nice and soft inside.
They go very well as a side dish to Rhenish bean soup (see my recipes) or to other sweet dishes such as rice pudding.
