You can never have too many fish fry recipes that leave the chef with half a bottle of beer to consume. Here are several more:

one egg
1/2 cup flour
1 tablespoon cornstarch
1/2 teaspoon salt
1 1/2 teaspoons baking powder
about 1/2 cup beer
Beat egg. Sift dry ingredients into egg and mix. Add beer until batter is a little thicker than the consistency of heavy cream. Dip fish pieces and fry in hot oil.

or...

one cup pancake mix
3/4 cup beer
