What You Need to Know
Acetic acid from vinegar denatures fish proteins while hydrolyzing collagen into gelatin, while Maillard reactions between onion sugars and amino acids create 2-furanmethanethiol and other aromatic compounds. Raisins contribute glucose and fructose for caramelization.
Simultaneously preserves fish while creating a complex balance of sweet (caramelized onions/raisins), sour (vinegar), and umami (hydrolyzed proteins).
