58.—Ship Biscuits.
These were evidently the first biscuits, from which have sprung all the varieties of hard biscuits which we at present possess. They are of the same character as those which were first made by man in his progress towards civilisation, and were baked or roasted on hot embers. Before this, men knew of no other use for their meal than to make it into a kind of porridge. Biscuits prepared in a simple fashion were for centuries the food of the Roman soldiers. The name is derived from the Latin bis, twice, and the French cuit = coctus, meaning twice baked or cooked.
Ship biscuits are composed of flour and water only; but some think a small proportion of yeast makes a great improvement in them. The method adopted is to make a small weak sponge as for bread previous to making the dough; the necessary quantity of water is then added. The flour used for the commoner sort of these biscuits is known as middlings or fine sharps; and those made from the finer or best are called captains or cabin biscuits. A sack of flour loses, by drying and baking, 28 lbs.
