I love this traditional British Fish Batter from https://sweetandsavorymeals.com:
Ingredients:
1 cup all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
1 cup beer
Instructions:
In a mixing bowl, combine the flour, baking powder, and salt.
Gradually stir in the beer until you get a smooth batter.
Let the batter rest for at least 30 minutes before using.
Dip your fish fillets into the batter and fry in hot oil until golden brown.
