Toast some good quality white bread (it has to be always white), butter it while still hot, and then spread some Marmite very thinly across the toast. Now cut it up into strips, 3/4in wide, and you have the British delicacy known as Marmite Soldiers, a variation on plain Toast Soldiers, ideal for dipping into a soft boiled egg.
For those of you who like potato chip sandwiches, another Brit delicacy, again use white bread and real butter (salted), spread Marmite thinly, and add plain potato chips as required. Now 'sandwich' the Marmite, butter and potato chips between another piece of buttered white bread.
Marmite is an accredited 'Vegetarian' product, and also approved as a Kosher product, even though not strictly 100% Kosher.
