A steak.

You should fry a steak in butter, exactly as you normally would fry your steak to your liking in butter. Except, also include a teaspoon of marmite in the butter.

Also, Tesco right now have a special edition aged Red Leicester cheese with marmite. This stuff is divine, almost any cheese that gets made with marmite is divine.

But grate a little of that beast out onto a cheese and tomato pizza before you cook it and it's a whole new ballgame.
