In the late sixteenth century, Sir Hugh Plat wrote, in his unpublished notes, of portable soup as a potential military rations for the army and navy, describing it as meat broth boiled down to a thick and dry paste which he called "Gelly". Plat's basic recipe was to boil the feet or legs of beef cattle for a long time to make "a good broath" which was then strained and boiled down to "a strong & stiff gelly". This in turn was dried on clean cloths in a windy place out of the sun, cut with wire into pieces, powdered with flour to stop the pieces from sticking, and stored in wooden boxes.
