Ceviche, also spelled cebiche in Peru, has deep roots on the Pacific coast, where seafood was seasoned and preserved with local acidic fruits long before limes became common. The modern Peruvian style developed through several culinary influences: citrus brought after European contact, onion and coriander used in coastal cooking, and the later refinement of a short, cold dressing time. That history explains why this version is dressed briefly rather than left to “cook” for hours.

The goal is not to cure the fish completely, but to keep its centre tender while balancing sharp citrus, chilli, onion, and the starchy sweetness of camote and corn.

For ceviche for six, plan on about 150 g of trimmed fish per generous main-course bowl, plus sides. In Spain, 900 g of sea bass, sea bream, or hake loin may cost roughly €22 to €45 depending on species and season; citrus, onion, chilli, coriander, sweet potato, corn, garlic, and ginger usually add €8 to €12. That puts the estimated total at about €30 to €57, or €5 to €9.50 per serving.

Buy the fish last, transport it in an insulated bag when needed, and maintain cold-chain control by refrigerating it below 4°C as soon as you get home. This supports raw fish safety without relying on lime juice as a safety measure.

Check raw-fish safety before you buy

Ask whether the fish is suitable for raw eating, confirm parasite control, and keep it below 4°C until cutting.

Choose a firm Spanish fish

Choose thick sea bass or sea bream fillets, as their firm flesh holds neat 1.5 cm cubes; hake needs gentler mixing.

Follow the parasite-control rule

If fish has not received appropriate parasite-freezing treatment, freeze it at home for at least five days at -20°C according to current Spanish consumer guidance.

For raw or lightly marinated fish in Spain, use a trusted supplier, confirm the parasite-control plan, keep the fish cold, and serve it immediately. Lime juice is flavour and texture, not a safety treatment.

Dress the fish just before serving

Prepare the garnish and cold leche de tigre first, then dress the fish for only 10 to 15 minutes.

Make a cold leche de tigre

Blend 180 ml lime juice, 40 ml lemon juice, coriander stems, garlic, ginger, chilli, 60 ml cold fish stock or water, salt, and four ice cubes; strain and chill.

Mix once and serve at once

Ten minutes before eating, cut the fish into 1.5 cm cubes, salt it, add onion, chilli, coriander leaves, and 220 ml cold leche de tigre, then fold gently and plate immediately.

Adapt Spanish substitutes without losing balance

Choose substitutions for flavour and texture while keeping the brief, bright Peruvian-style dressing.

Swap ingredients with a clear purpose

Use cooked sweet potato for camote and large-kernel corn for choclo; use red chilli and a little habanero as an ají limo substitute.

Keep the meal safely shareable

Serve a cooked fish alternative to guests who are pregnant, immunocompromised, very young, or advised to avoid raw or lightly marinated fish.

⚠️ Do not keep leftovers for the next day. This dish is designed for immediate service, and extra citrus time makes both texture and safety harder to manage.

Regional ceviches share raw or lightly cured seafood, but they do not taste alike. Peruvian ceviche usually uses firm white fish, a short 10- to 15-minute contact with citrus, chilli, red onion, coriander, and a liquid leche de tigre, with sweet potato and corn on the side. Mexican ceviche commonly includes tomato, avocado, cucumber, and sometimes a longer lime cure, producing a wetter, more salad-like result.

Chilean ceviche often relies on local fish such as corvina or reineta with onion, coriander, and citrus, while seasoning and marinating time vary by region. For this recipe, use the short Peruvian-style timing to preserve clean fish texture.

FAQs

How do I make ceviche for 6?

Use 900 g trimmed white fish, 300 ml fresh citrus juice, one large red onion, chilli, coriander, sweet potato, and corn. Keep fish cold and dress it 10 to 15 minutes before serving.

How much fish do I need for six people?

Use 900 g of trimmed fish for six generous main-course servings. Use 600 to 720 g if ceviche is one of several shared plates.

Can lime juice make raw fish safe?

No. Lime changes flavour and texture but does not replace freezing, refrigeration, or hygienic handling.

Can I use hake for ceviche?

Yes, thick hake loin can work with the correct parasite-control treatment, but cut and mix it gently because it flakes easily.

How long should ceviche sit in lime?

For this method, let fish sit in cold dressing for 10 to 15 minutes. Longer marinating makes the outside firmer and often dry.

What can I use instead of ají limo?

Use red chilli for colour and fruitiness, then add a small piece of habanero for heat.

Can I prepare ceviche ahead for a party?

Prepare vegetables, sides, bowls, and leche de tigre up to 45 minutes ahead, but cut and dress fish only shortly before eating.

The essentials: use 900 g of trimmed firm fish for six generous bowls. Keep fish below 4°C and confirm parasite prevention before marinating. Make the leche de tigre and side dishes ahead, then dress fish for only 10 to 15 minutes. Treat lime as seasoning, never as a safety shortcut.
