Wine dough is suitable for baking various ingredients in the deep fryer. Mix flour and white wine to a smooth dough. Stir the egg yolk into the wine dough and season with salt. Beat the egg whites until stiff and fold in loosely with a whisk. Do not stir too much so that the foam does not collapse and the wine retains its airy consistency. The amount of wine dough is enough for 500 g of meat, fish, vegetables or fruit.
