I very nearly put Tesco not-Marmite in my list as I have it on toast for breakfast every week day.Wera for screwdrivers and bits.
Marmite for yeast spread.
It was previously the real thing, but when there was a shortage (during Covid. I think) I reluctantly bought the Tesco variant that, I'm sure, comes out of the same factory. Turned out I preferred it, primarily because it's more spreadable. I'd be interested to do a blind taste test on the two.
