Wash the fish fillets, dry them and cut them into larger cubes.
In a bowl, mix eggs with sour cream, season (salt, pepper, nutmeg) and carefully mix in flour. Blend all ingredients together with a whisk to form a smooth batter. Dip the fillets in batter and then in breadcrumbs mixed with dried parsley. Put them on skewers and fry on all sides in hot oil. Drizzle with lemon juice when serving.
