When Marmite first came out it was used for all sorts of things which we might now think of as odd - I saw a TV program about things which were new foods when introduced.

There were Marmite cookbooks, where everything was mixed with the stuff.

Vegetarians took to marmite in a big way and put it into vegetable stews to give some 'bite' to the flavour, made a gravy to pour over shredded wheat for breakfast - the combination was then baked for a few minutes so the top was crispy and the underside soft.

Oh drat - now I have visions of a thick crust of home baked bread, still hot from the oven, with butter melting into it, lightly laced with Marmite.
