In 2005, The Daily Telegraph reported the invention of a device for cutting bread into soldiers.

[4] There is an early reference from 1728 in England to a "garnish of fry'd Bread, cut the length of one's Finger", as an accompaniment to boiled tench.

In 1868 Alphonse Daudet mentions mouillettes in the novel Le Petit Chose: "A sa gauche, Annou lui taille des mouillettes pour ses oeufs, des oeufs du matin, blancs, crémeux, duvetés".

The modern phrase first appeared in print in 1966 in British writer Nicolas Freeling's novel The Dresden Green (where it is used to eat soup).

It is possible that it was either popularised or invented in 1965 in a series of TV advertisements for eggs starring Tony Hancock and Patricia Hayes.
