Fried foods are something from which I generally stay away. However, everyone has something for which they will cave.
Frying anything is time consuming but not difficult. Probably a good thing it is so messy, that alone keeps me from frying anything frequently.
1 small can of beer, room temperature
1 large egg
1 teaspoon salt
pinch black pepper
pinch dry mustard powder
1-2 cups all purpose flour or spelt
oil for frying
If you have a little (or large) fryer that's nice, I don't, I use what I have because I have no where else to store things I only use occasionally.
Pour at least 3 inches of oil into a medium/large sauce pan. Using a candy thermometer, bring oil up to 350F. watch and adjust the temperature as necessary.
Mix everything except the flour in a large, shallow bowl.
