1 1/3 c All-purpose flour
1 t Salt
1/4 t Pepper
1 T Oil
2 Egg yolks
3/4 c Beer

Mix the flour, salt, pepper, oil and yolks together. Gradually whisk in the beer. Refrigerate the batter 3 1/2 hours to rest before using. Dip fish or sliced onions in batter. Deep-fry in 375f oil until golden brown. This batter also works well on other vegetables besides onion rings.
