Here is everything you never wanted to know about Marmite, lol. I have never had it, is it as unsavory as it sounds?
Marmite is the name given to two similar food spreads: the original British version, first produced in the United Kingdom and later South Africa, and a version produced in New Zealand. Marmite is made from yeast extract, a by-product of beer brewing.
The British version of the product is a sticky, dark brown paste with a distinctive, powerful flavour, which is extremely salty and savoury. This distinctive taste is reflected in the British company's marketing slogan: "Love it or hate it." Other similar products are the Australian Vegemite and the Swiss Cenovis.
The distinctive product was originally British, but a version with a different flavour has been manufactured in New Zealand since 1919, and this is the dominant version in New Zealand and the Pacific Islands.
