Acidic “cooking” denatures fish proteins, producing a cooked texture without heat.
Origin: Pre‑Columbian indigenous peoples (Before European citrus introduction) — Andes and Amazon
See full technique reference →At pH 2–3, fish myofibrillar proteins unfold and aggregate, forming a coagulated matrix similar to heat‑cooked fish. Bromelain in pineapple further cleaves myosin, accelerating texture changes. The resulting pH 3.5–4.0 inhibits most spoilage bacteria, and refrigeration for 24 h reduces Listeria and Salmonella by >5 log.
