Makes enough batter to coat about 2 pounds fish or chicken or vegetables.
Sift together flour, cornstarch, baking powder and baking soda. Stir in water, then egg; beat with rotary beater or wire whip until smooth and frothy. For an even better fry... dredge the meat or vegetable in milk then plain flour, then refrigerate for 1-2 hours before dipping in Tempura.
[Use ice water in tempura batter. The colder it is the better the results. S.C.]
