Description
A preservation method using salt dehydration and controlled fermentation to transform cod into a stable, flavorful product.
Technical
Osmotic dehydration through salt draws out moisture while inhibiting microbial growth, with endogenous proteases (calpains, cathepsins) slowly breaking down muscle proteins into free amino acids and peptides. Lipolysis generates free fatty acids that oxidize into volatile compounds.
Culinary Significance
Creates a dense, flaky texture with concentrated umami and oceanic flavors that rehydrate into versatile ingredients.
