Description
Enzymatic and evaporative concentration of cod proteins and lipids through Arctic wind exposure.
Technical
Lipolysis and proteolysis occur slowly at low temperatures (2-10°C), with Maillard reactions limited by minimal solar radiation. Glutamic acid concentration increases 3-5x through moisture loss.
Culinary Significance
Creates shelf-stable protein with intense umami and chewy texture, foundational to Nordic lutefisk and Portuguese bacalhau dishes.
