Salt-curing and lactic acid fermentation preserve fish, creating a salty, umami-rich product.
Origin: Norse (Viking Age (8th–11th c.)) — Iceland, Norway, Sweden
See full technique reference →Proteolytic enzymes hydrolyze proteins into peptides and free amino acids, while lactic acid bacteria ferment residual sugars to lactic acid, lowering pH to 4.0–4.5 and inhibiting pathogens.
Primary Reaction
Lactic acid fermentation of residual sugars and proteolysis of fish proteins
