This is a quick and easy recipe for a beer batter that goes great with nearly any fish or seafood; it's basically a fish 'n' chips batter made with a good beer, flour and a little oil. The keys here are cold batter, hot oil and quality fish. This recipe works well with tilapia, cod, haddock, walleye, sea bass, snapper, halibut, just about any firm fish. You can even use it for shrimp, calamari or oysters. Serve this with french fries and a dipping sauce. We like simple mustard. This recipe makes enough batter for 2 pounds of fish or seafood.
