Garum

Garum is a fermented fish sauce that was used as a condiment in the cuisines of Phoenicia, ancient Greece, Rome, Carthage and later Byzantium. Liquamen is a similar preparation, and at times they were synonymous. Although garum enjoyed its greatest popularity in the Western Mediterranean and the Roman world, it was in earlier use by the Greeks. The taste of garum is thought to be comparable to that of today's Asian fish sauces.

Like modern fermented fish sauce and soy sauce, garum was a rich source of umami flavoring due to the presence of glutamates. It was used along with murri in medieval Byzantine and Arab cuisine to give a savory flavor to dishes. Murri may derive from garum.
