Marmite
Despite its texture, taste and smell, Marmite endures as an extremely popular if not divisive food spread in the UK, as well as other countries that have their own derivatives of it. Sold under the slogan "Love It or Hate It," Marmite is a sticky, salty yeast extract that's traditionally served on bread or as an ingredient in the world's most disgusting sandwiches (or "sarnies" as Brits would have you believe).
