This recipe is one I found in an old volunteer fire department cookbook from Southern Indiana.
2 eggs, beaten
1 cup milk
1 1/2 cups all-purpose flour
2 tsps baking powder
1 tsp salt
In a small mixing bowl, place the beaten eggs. Add the milk to the eggs and blend well. Mix together the flour, baking powder and salt. Add to the milk and egg mixture. Heat oil to approximately 350-360 degrees. Dip fresh fish fillets into the batter, then gently drop into the hot oil. Fry until golden brown and fillets rise to the top of the oil. To keep your oil from cooling down too much, only add a couple of pieces of fish at a time. After removing fish from the oil, drain on paper toweling for a couple of minutes.
This batter is also great for making fried onion rings, fried zucchini, etc.
