This may be off topic but try a little english mustard with your marmite on toast, a taste sensation.
I have Dijon in the fridge but both brands are fantastic, both will remove the nose from the face at any particular time.
I'm a regular of the marmite & peanut butter taste sensation but that sounds er... intriguing. Btw when your making up the powdered mustard try it with tonic water or vinegar
