Marmite
Marmite is a dark-brown coloured savoury spread made from the yeast extract a by-product of the brewing industry. It has a strong, slightly salty flavour. You either "love it or hate it". Can be eaten spread thinly on toast.
I like the "can" above, rather than "is" or "should" or "enjoyed when".
Marmite is great if you like savoury stuff. It's a healthy way of making a slice of plain toast interesting in the morning. Even delicatessen/posh sandwich shops in London will ask you how thick you want it spread - some like it trowelled on, and others just like a whiff shown to the bread. Ahh, marmite rituals eh?
White pudding and Irish breakfast anyone? lol...
