For the sauce, heat the butter in a pan. On reduced heat, fry the gingerbread crumbs, nuts, almonds, raisins and prunes. Stir in the honey. Spoon in some of the fish stock until the sauce is thick. Pour in the beer and let simmer until the sauce is thick and creamy. Add optional powidl.
Put the carp fillets back in the sauce, turning them over once. Warm them up in the sauce on low heat.
