Marmite is a British product generally spread thinly on buttered toast and eaten. It can also be made into a savoury hot drink by adding one teaspoon to a mug of hot water. The product itself is made from yeast extract, a by-product of beer brewing; and is a sticky, dark brown paste with a distinctive, powerful, salty flavour. It is a rich source of the vitamin B complex and Folic acid. Due to its unusual taste people tend to either love or hate it. Marmite is similar to Australian Vegemite and the American Vegex spread.
