Best way to eat/ appreciate Marmite is to spread it thinly on toast underneath either scrambled or poached eggs! Fab! Add baked beans if you must.
Otherwise it has become a (deomcratic?) thing - Love it or loathe it.
Or irrepressibly associated with that Marmitevellous song, "The gravy's with the Bovril, and the Marmite's with the jam".
