PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Ceviche is a dish where raw fish is cured in citrus juice, turning it opaque and firm through acid denaturation.
Origin: Peruvian (Pre-Columbian) — Peru
See full technique reference →The citric acid in lime juice lowers the pH to around 2.5–3.0, causing myosin and actin proteins to denature and coagulate. This process mimics heat‑induced denaturation but occurs at ambient temperatures. The resulting protein network traps water, giving the fish a firm texture while preserving its raw flavor.
Primary Reaction
Acidic denaturation of fish muscle proteins (myosin, actin)
