Real recipe straight from the UK:
■4 cod fish fillets or 4 haddock fillets
■6 ounces plain flour
■1 teaspoon bicarbonate of soda
■1 (8 fluid ounce) bottle English beer, Small
■1/2 lemons, juice of
■salt & pepper
■extra flour
Put some flour onto a plate. Dredge the fish fillets in the flour thoroughly this is VERY important, it stops the batter sliding off when fried! Leave the fish fillets in the flour whilst you make the batter.
Some people say you should make the batter at least one hour before I have found little difference so make it before if it is convenient or now.
Put flour, bicarbonate of soda, salt and pepper into a large roomy bowl. Add the beer gradually, stop when you have a thick coating type of batter. Drink any beer that is left! Whisk thoroughly until it is smooth and there are no lumps. **Add** the lemon juice OR a splash of **malt vinegar** if desired. Mix thoroughly again.
Have your plates, newspaper or whatever ready for eating.
Adjust deep fat fryer to fish frying temperature of 160ฐC.
Take one fillet of fish at a time and holding it by the tail or the thin end (!) swirl it around the batter until well coated plunge into hot fat immediately. As soon as it has crisped up and set, add your other fillets one at a time, taking out the first ones as they cook about 6 to 10 minutes depending on the thickness. Place onto a tray and keep warm in the oven.
