Mmmm how do I like marmite... I can't list that many things, no really, it's like how many evil things can you think of to do to George Bush... it's nearly endless.
A few greats:
In cheese straws
With Brie on toast
Thick fresh toast with butter and a thin spread of marmite.
Cheap cardboard toast and LOTS of marmite
Always remember with much fondness when the obnoxious german exchange student came to stay.. and thought I was allowed chocolate spread on my toast. First big mouthful, and an expression I will remember for ever.
