SNAILS

Wild snails may be caught, and then fed on a mix of flour and herbs for seven days to clean them before being cooked and eaten. To cook the snails they are dropped, live, into boiling water, blanched, and then rinsed in a mixture of vinegar and water before being slow cooked in a stock, and traditionally served with a garlic butter sauce. British garden snails were eaten in Britain until the Industrial Revolution, but are rarely caught and eaten now in Britain, though some restaurants do buy snails from farms where they are reared for consumption.
