Love marmite, and do not feel the need to spread it thinly :-)
Also love twiglets. Used to suck Oxos when I was a kid, but have not done so for some time.
Apparently, things with a lot of B vitamins (like Marmite) make your pee more yellwo than normal,
so you may be hydrated even when pee is yellow, if you've eaten lots of MM.
BTW, it is woth mentioning that a lot of real ales contain a lot of vitamins.. :-)
