What Is Ceviche? The Dish That Cooks Without Heat

Ceviche is a cold dish of raw fish marinated in citrus juice until the acid firms the flesh and turns it opaque, the way heat would. No stove is involved. Sliced onion, chili, and salt sharpen the marinade. The dish is most closely tied to Peru, where it is a point of national pride, but versions thrive all along Latin America’s Pacific coast. Even the name is a friendly puzzle: scholars have traced it to the Quechua word siwichi and to the Spanish escabeche, a vinegar marinade with Persian roots.

A short history

The story starts long before limes reached the Americas. On Peru’s northern coast, the Moche people were eating fresh fish cured with local fruit juices and chili some two thousand years ago. Spanish colonists later brought limes and onions, and the modern marinade took shape. Who perfected it is a warm dispute: Peru and Ecuador both claim ceviche as their own, and each makes a proud case. The truth is probably tangled in both. Peru has leaned in hardest: it declared ceviche part of its national heritage in 2004 and celebrates a national ceviche day every June 28. In 2023, UNESCO added Peruvian ceviche traditions to its list of intangible cultural heritage.

What’s in it?

Classic Peruvian ceviche needs just a handful of things: fresh white fish such as corvina, lime juice, red onion, ají chili, cilantro, and salt. The fish marinates briefly (many cooks swear by mere minutes) and the leftover citrus marinade, milky with fish juices, is prized as leche de tigre, or tiger’s milk. Sides do real work here: slices of sweet potato, large-kernel corn called choclo, and crunchy toasted corn balance the acid. Regional riffs abound: Ecuador often adds tomato and serves shrimp versions, while Mexico spoons its ceviche onto crisp tostadas with avocado.

How do you eat it?

In Peru, ceviche is lunch food. Cevicherías (casual restaurants built around the dish) traditionally open at midday and sell out by late afternoon, because the fish should be eaten the day it was caught. You eat it with a spoon or fork, alternating bites of tangy fish with sweet potato and corn to rest your tongue. Finishing the leche de tigre is encouraged; some drink it straight from a small glass and call it a hangover cure. Pair it with something cold, take your time, and sit near the sea if you can manage it.
