Anonymous, The art and mystery of curing, preserving… (1864)
“ As to the length of time the fish should remain in the pickle, that depends whether they came to hand with coarse salt scattered amongst them, at the sea coast, a precaution necessary in hot weather; a good criterion is when the fish begin to be stiff or rigid while being handled, but to try one or two cooked is certainly a sure proof. Pure fresh water must never be added or made use of in this process after salt has been imbibed, or the heads will all be broken when putting them on the spits. ”
