Tempura Batter

1 egg, beaten
1 cup ice cold water
1 cup flour

2 tablespoons dry white wine (optional)

Whisk together. The batter should be lumpy.

Dip something in the batter and deep-fry it.
Dust vegetable slices in flour before dipping them in the batter.

You can make a dipping sauce from dashi, mirin, sake, soy sauce and ginger, or just use plain soy sauce.
