What You Need to Know
Acetic acid (2-8% concentration) disrupts hydrogen bonds in myofibrillar proteins, causing partial unfolding while NaCl (15-20% brine) controls water activity. Eugenol from cloves and terpenes from bay leaves diffuse into muscle tissue.
Creates shelf-stable fish with tender texture and balanced acidity that cuts through the fish's natural oiliness.
