This is a St. Louis tradition found in most local pizza places. You can get an order of this with your pizza instead of bread sticks and they also sell it in the grocery stores. I found this recipe on the back of a bag of Seviroli frozen ravioli.
12 frozen ravioli squares, thawed
1/4 cup whole milk
1 large egg
3/4 cup seasoned bread crumbs
1 1/2 cups vegetable oil for frying
1 T. grated Parmesan cheese
8 oz. prepared marinara sauce
1/4 tsp. salt optional
Put the marinara sauce in a pot on low/medium heat, stirring occasionally. Whisk milk and egg in a small bowl to make egg/milk batter. Place bread crumbs and salt in shallow bowl. Dip thawed ravioli into the batter and coat with bread crumbs. Heat the oil in a heavy frying pan until the oil sizzles. Fry the ravioli one at a time, one minute on each side or until golden brown. Drain well and sprinkle with Parmesan cheese. Serve with the marinara sauces as a dip. Serves 4.
