Soak the raisins in the water.
Grate the peel from half of the lemons and set aside. Squeeze the lemon. For 50 fresh vine leaves, boil 3/4 liter of water with the vegetable bouillon cube and 2 tablespoons of juice of one lemon. For pickled vine leaves, without the stock cube. Blanch the vine leaves in the liquid for 2-3 minutes and drain.
Measure out 100 ml of the blanching stock per person and pour it into a saucepan together with the wine. Add the cornmeal and salt, bring to the boil and swell to a thick paste in about 5 minutes. Spread half of the butter in flakes evenly on the hominy. Stir the eggs, 1 tablespoon of lemon juice, zest, ginger and raisins with the soaking liquid into the hominy.
Dice the onions and sauté them in a little butter. Now add the hazelnuts and fry for about 3 minutes. Stir everything into the hominy. Season lightly with the spices.
Place 2-3 vine leaves on a plate on top of each other so that the shiny side is facing down and the stalks overlap. Just under 1 tbsp. of filling on the leaves form and roll them up. Place the rolls end to end in 2 cooking pans. Pour 4 tbsp. juice of one lemon and 200 ml water over the rolls. Put a thin slice of butter on each roll. Cook the vine leaves for 8-10 minutes at low temperature with the lid closed and then leave them on the plate for another 5 minutes.
