Just wanted to give a somewhat personal note on Marmite. When I was little (this is how every story I tell to my kids starts...) I was rummaging through my mother's cabinets and sampling everything in sight - I was very interested in the container that said cocoa and smelled like chocolate... (in which my brain excluded the word "unsweetened") Finally in the spice section, there was this very small jar - brown glass with a yellow lid (don't ask me why I remember that) Naturally, I opened it - and ewwww. Marmite smells terrible. I asked mom what it was - she said it was for coloring gravy. I am sure she has used it maybe twice in her life, since at a tender age, I took over the cooking - simply for self defense.
