Hardtack, the other staple of the sailor’s execrable diet, consisted of coarse wheat flour, including the husk, kneaded with hot water (never cold), and cooked twice. The result, a tough, brittle biscuit known as biscocho, was stored for up to a month before it was sold. Inevitably, the hardtack degraded in the humid conditions at sea, and when it became soft, and rotten, and inedible, it was called mazamorra; the sailors boiled the stuff until it turned into a mush known as calandra, said to be so vile that even starving sailors refused it.
