Fish sauce recipe
46. Making gara.
The so-called liquamen is made thus. Fish entrails are put in a container and salted; and little fish, especially sand-smelt (atherina) or small red mullet or mendole (picarel = spicara maena) or anchovy, or any small enough, are all similarly salted; and left to pickle in the sun, stirring frequently. When the heat has pickled them, the garos is got from them thus: a deep close-woven basket is inserted into the centre of the vessel containing these fish, and the garos flows into the basket. This, then, is how the liquamen is obtained by filtering through the basket; the residue makes alix.
The Bithynians make it thus. Take preferably small or large picarel , or, if none, anchovy or scad or mackerel, or also alix, and a mixture of all these, and put them into a baker’s bowl of the kind in which dough is kneaded; to one modios of fish knead in 6 Italian pints of salt so that it is well mixed with the fish, and leaving it overnight put it in an earthenware vessel and leave it uncovered in the sun for 2 or 3 months, occasionally stirring with a stick, then take [the fluid?], cover and store. Some add 2 pints of old wine to each pint of fish.
If you want to use the garon at once, that is, not by ageing in the sun but by cooking, make it thus. Into pure brine, which you have tested by floating an egg in it (if it sinks, the brine is not salty enough) in a new bowl, put the fish; add oregano; place over a sufficient fire, until it boils, that is, until it begins to reduce a little. Some also add grape syrup. Then cool and filter it; filter a second and a third time until it runs clear; cover and store.
A rather high quality garos, called haimation, is made thus. Take tunny entrails with the gills, fluid and blood, sprinkle with sufficient salt, leave in a vessel for two months at the most; then pierce the jar, and the garos called haimation flows out.
