Ceviche: The Acid Cook That Changed the World

Peruvian ceviche — fresh raw fish "cooked" in leche de tigre (tiger's milk: lime juice, chilli, onion, coriander, fish stock) — is the dish that put Peru on the global culinary map. The acid in the lime juice denatures the fish protein (the same chemical transformation as heat-based cooking, but at room temperature), turning the flesh opaque and firm. Modern Peruvian ceviche is served within minutes of preparation — the fish should be fresh-cut, briefly bathed in leche de tigre, and served immediately. The "cook" time is 2–5 minutes at most. This is not the hours-long marination of Ecuadorian or Mexican ceviche — it is a flash preparation.

- **Fresh fish, not frozen.** The fish must be sashimi-grade — fresh enough to eat raw, because it essentially IS eaten raw. The lime juice changes the texture and appearance but does not sterilise the fish. - **Minutes, not hours.** Peruvian ceviche is dressed and served. A 30-minute marination produces an overcooked, rubbery result. The target is firm on the outside, still slightly translucent in the centre. - **Leche de tigre is the liquid gold.** The marinade liquid — lime juice infused with chilli, onion, coriander, salt, and often a splash of fish stock — is served alongside as a drink or spooned over the fish. It is considered the best hangover cure in Peru. - **Ají amarillo (yellow chilli) is the Peruvian signature.** The specific fruity heat of ají amarillo distinguishes Peruvian ceviche from all others. Without it, you have lime-marinated fish. With it, you have ceviche.
