The nuts (I took the same amount of walnuts and almonds) are washed and fried in a frying pan for a few minutes. Wash the raisins, you can soak it overnight in alcohol. I didn’t soak it, but I added 1 tablespoon of cognac, melting the chocolate. Grind the nuts in a coffee grinder, grind together with the raisins in a blender and mix with melted chocolate. If the filling is very thick, add 2-3 tablespoons of alcohol or milk.
