Fermented fish in salt and herbs (North Africa)

Description

A traditional North African fish fermentation that uses salt and herbs to promote halophilic lactic acid bacteria, producing a salty, umami, and slightly sour paste.

Technical

Halophilic lactic acid bacteria hydrolyze fish muscle proteins into free amino acids and peptides, generating lactic and acetic acids that lower the pH to about 4.5. The resulting acidic environment preserves the fish while the phenolic antioxidants from herbs inhibit oxidation and suppress spoilage microbes. The combination of proteolysis, acidification, and antioxidant activity creates the characteristic umami, salty, and herbal flavor profile.
