Ceviche:

Ceviche is the emblem of coastal Peru: austere and bright, as much a story as a dish. At its heart, it’s raw fish briefly marinated in citrus with chili, salt, and red onion, served cold with sweet potato and corn. But that simplicity hides centuries of exchange, migration, and technique.

How ceviche became ceviche

- Pre-Columbian origins: Long before limes arrived, northern Peru’s Moche (Mochica) and later coastal cultures enjoyed ultra-fresh fish and shellfish seasoned with salt, ají (chili), and acidic fruits and fermented drinks like chicha. This was a fast preparation—caught, dressed, and eaten on the shore.

- Spanish arrival (16th century): Conquistadors brought citrus—especially the small, intensely acidic limón sutil (akin to Key lime)—and new preservation ideas from the Arabic-influenced Iberian tradition of escabeche. The word ceviche/seviche/cebiche may stem from Spanish escabeche or from the Quechua term siwichi (fresh fish). The lime transformed the flavor structure and set today’s signature acidity.

- Afro-Peruvian and criollo kitchens: Techniques for salting, marinating, and balancing sweetness and heat matured in coastal households and markets, refining the cut of the fish, the brief curing time, and the garnishes (sweet potato, corn, cancha).

- Japanese and Chinese influence (late 19th–20th centuries): The Nikkei and chifa communities refined knife work, texture, and minimalism. Tiradito—sashimi-like slices dressed just before serving—shows this influence.

- Modern Peru: Ceviche is a national symbol. June 28 is Día Nacional del Ceviche. Lima’s cevicherías fine-tuned timing, temperature, and the concentrated citrus-chili emulsion called leche de tigre.

The technique: what makes Peruvian ceviche different

- Fish selection: Lean, very fresh, mild, and firm: sea bass/corvina, fluke, halibut, mahi, or snook. Oily fish (mackerel, salmon) are better for other styles. Shellfish ceviche is common too.

- Cut: Uniform 1–2 cm cubes for classic ceviche; thin slices for tiradito; bite-size for mixto. Cold, sharp knife; remove sinew.

- Onion: Red onion, very thinly sliced (pluma), rinsed briefly to tame bite, then well dried.

- Chili: Ají limo or rocoto for heat; ají amarillo for fragrance and color. Seeds removed for balance.

- Citrus: Freshly squeezed Peruvian limón is ideal; elsewhere, Key lime or a blend of Persian lime and a splash of bitter orange. Avoid premade juice; strain to remove bitter oils.

- Seasoning order: Salt and fish first (begins firming), then chili and onion, then cilantro, and citrus last. Taste, adjust, and serve quickly.

- Time: Peruvian ceviche is fast—2 to 10 minutes in acid. Longer “cooking” drifts toward other Latin American styles and loses snap.

- Temperature: Everything cold. Chill bowls and plates.

- Leche de tigre: The milky juice that forms—lime, fish juices, salt, chili, and onion—sometimes blended with fish trimmings and a touch of ice for body. It’s both marinade and sauce.

Food safety and sustainability

- Acid doesn’t kill all pathogens or parasites. Use sushi-grade fish or fish that has been properly frozen for parasites (−20°C/−4°F for 7 days, or per local guidance). Keep below 4°C/40°F.

- Buy from reputable, sustainable sources; avoid overfished species.

- If uncertain about raw fish, try mushroom or hearts-of-palm “ceviche.”

Classic Peruvian ceviche (serves 2)

Ingredients:

- 300 g very fresh firm white fish, skinless

- 1–2 ají limo or 1 serrano, finely minced

- 1 small red onion, thinly sliced, rinsed, dried

- 8–10 limes (Key if possible), juiced and strained (about 120 ml)

- 6–8 sprigs cilantro, chopped

- Fine sea salt

- Optional: small piece of celery, ginger slice, and fish trimmings for leche de tigre

- To serve: cooked sweet potato slices, boiled choclo (Peruvian corn) or large-kernel corn, cancha (toasted corn), lettuce, yuyo (seaweed) if available

Method:

1) Prep fish: Chill everything. Cut fish into 1.5 cm cubes. Lightly salt and rest 2 minutes.

2) Aromatics: In a cold bowl, combine fish, chili, and onion. Add half the cilantro.

3) Citrus: Add enough lime juice to just submerge. Toss gently. Taste salt; adjust.

4) Time: Let stand 2–5 minutes until edges turn opaque but center remains tender.

5) Serve: Plate fish with onion and a ladle of the leche de tigre. Garnish with remaining cilantro. Add sweet potato, corn, and cancha.

Optional richer leche de tigre: Blend 60 ml lime juice with a few fish trimmings, a slice of ginger, celery, a chili slice, ice cube, pinch of salt; strain over the fish.

Tiradito with ají amarillo (serves 2)

Ingredients:

- 250 g very fresh fluke or corvina, trimmed

- Sauce: 60 ml lime juice, 1 tbsp ají amarillo paste, 1 tsp fish stock or ice-cold water, pinch salt, drop of neutral oil

- Garnish: paper-thin red onion, cilantro leaves, thin sweet potato slices, cancha

Method:

1) Slice fish thinly on the bias like sashimi; arrange on a cold plate.

2) Whisk sauce until lightly emulsified; taste for heat and acidity.

3) Spoon sauce over fish right before serving. Garnish and serve immediately.

Ceviche mixto (fish and shellfish, serves 3–4)

Ingredients:

- 250 g firm white fish, diced

- 200 g raw shrimp or small squid rings (briefly blanched 30 seconds if preferred)

- 1–2 ají limo, minced

- 1 red onion, thinly sliced, rinsed

- 150 ml lime juice, strained

- Cilantro, salt

- Optional: a few drops of fish stock for umami

Method:

1) Combine fish, shrimp/squid, chili, onion, and salt in a cold bowl.

2) Add lime juice to cover; toss gently. Rest 5–8 minutes (shellfish may need a touch longer).

3) Finish with cilantro; serve with sweet potato and corn.

Leche de tigre shooters (2 small glasses)

Ingredients:

- 120 ml fresh lime juice

- 50 g fish trimmings or a spoon of diced fish

- 1 tbsp chopped red onion

- 1 small piece celery

- 1 slice ginger

- 1–2 slices ají limo

- Pinch salt, ice cube

- Optional: a splash of evaporated milk for a creamy “leche de pantera” style

Method:

Blend all until frothy and very cold; strain. Pour into small glasses. Garnish with a cilantro leaf and a mini shrimp if desired.

Plant-based “ceviche” (mushroom or hearts of palm, serves 2)

Ingredients:

- 250 g firm mushrooms (oyster or button), thinly sliced, or 1 can hearts of palm, sliced

- 1 red onion, thinly sliced, rinsed

- 1 chili (ají amarillo or serrano), minced

- 80–100 ml lime juice

- Cilantro, salt, olive oil

- Optional: cherry tomato halves, diced avocado

Method:

1) Toss mushrooms or hearts of palm with salt, chili, onion, and lime juice. Rest 10–15 minutes.

2) Finish with cilantro and a drizzle of olive oil. Serve with corn and sweet potato.

How it relates to Peru—beyond the plate

- Geography on the tongue: The cold, nutrient-rich Humboldt Current feeds Peru’s fisheries, giving ceviche its incomparable freshness.

- Culinary identity: Ceviche is shorthand for Peruvian coastal cuisine—salty sea, bright lime, fiery ají, and crisp onion. It bridges Indigenous ingredients, Spanish citrus, and Asian knife work.

- Everyday ritual: Eaten at lunch when fish is freshest, in markets and cevicherías. It’s restorative—Peruvians joke that leche de tigre cures heartbreak and hangovers.

- Celebration and economy: June 28 is National Ceviche Day, spotlighting fishermen, farmers (corn, sweet potato, ají), and cooks across the coast and Amazon basins where river-fish ceviches appear.

- Regional Peru on a plate: Northern ceviches may include chicha de jora notes and slightly longer cures; Lima style is very quick and lime-forward; Amazonian versions use river fish and jungle citrus.

Tips for mastery at home

- Use more limes than you think; strain and keep cold. Taste constantly.

- Salt the fish before lime to firm and season evenly.

- Keep the cure short for snap; if you prefer more opacity, extend by a minute at a time.

- Balance heat: start with less chili; you can’t un-spice it.

- Garnish for contrast: sweet potato’s sweetness and corn’s starch balance acid and heat.

Ceviche is simple, but not easy: the discipline is in sourcing, knife work, temperature, and timing. Do those well, and in a few minutes you’ll taste a centuries-long Peruvian story—cool, bright, and alive.
