2 lbs. skinless fillets (cod, haddock, whiting, etc.)
1 c. buttermilk
1 c. biscuit mix
2 tsp. salt

Cut fillets into serving size portions. Place the portions in a single layer in a shallow baking dish. Pour buttermilk over portions and let stand for 30 minutes, turning once. Combine biscuit mix and salt. Remove portions from buttermilk and roll in biscuit mix to coat. Fry in 350 to 375 degree cooking oil for 4 minutes or until golden brown. Turn carefully and fry the same on the other side. Drain on paper towels. Serve with lemon wedges.
