I've used dozens of recipes over the years, searching for the "perfect fish batter" for fried fish. The many variations of "beer batter" always fell short for me (kinda strange taste, but then, I don't like beer). Actual Tempura batter just didn't have quite the substance I wanted either, although it was closer to what I wanted. I can't even eat some of the gummy, nasty battered fish I've been served and have made. This is honestly the best fish I've ever eaten, bar none, and that includes everyplace on the Pacific coast I've paid to eat. This is light, puffy, delicate and sticks to the fish.
The fish must be very cold and very dry. This will batter about 1 1/3 lbs of fish fillets. It's wonderful for shrimp too.
