Description
Dry-cured salmon with dill and sugar that preserves the fish by drawing out moisture and lowering water activity.
Technical
The salt draws water out of the fish by osmosis, reducing water activity below 0.85 and inhibiting pathogenic bacteria. Simultaneously, lactic acid bacteria ferment residual sugars, producing lactic acid that lowers the pH to 5.5–6.0 and adds a mild tang. The combined effect preserves the fish while imparting a delicate sweet‑salty, herbaceous flavor.
