Description
Garum is a fermented fish sauce produced by enzymatic hydrolysis of fish entrails in a high‑salt brine, generating free amino acids that impart strong umami.
Technical
During fermentation, endogenous proteases and halophilic bacteria hydrolyze fish proteins into peptides and free amino acids, especially glutamic acid, which confers the characteristic umami flavor. The process relies on a controlled salt concentration and ambient temperature to favor beneficial microbes while suppressing spoilage organisms, culminating in a clear, aromatic liquid after straining and brief post‑fermentation aging.
