At a small cevichería in Miraflores, service can begin as early as 11:30 in the morning. A cook cubes a slab of white fish, pours pale orange leche de tigre over it, counts quietly, then slides the plate across the counter. Six minutes from knife to spoon. In Peru, ceviche is a fast dish, not a marinade.
Mexican tostadas de ceviche often leave fish sitting in lime for an hour, until it turns opaque and firm all the way through. Peruvian ceviche is a different animal, and the gap between the two versions is a good reminder of how much regional habit shapes a single dish.
The Lima template goes like this. Ají limo, a small yellow-red Peruvian chile, carries the heat. Key limes do the cure. The whole thing happens in minutes.

Ingredients
For the leche de tigre and ceviche
- 500 g very fresh skinless white fish (corvina, sea bass, fluke, or halibut), cold from the fridge
- 12 key limes (about 180 ml juice), or 8 Persian limes plus zest as backup
- 1 ají limo, seeded (or half a yellow habanero as substitute)
- 1 small clove garlic, peeled
- 1 cm piece fresh ginger, peeled
- 1 small red onion, sliced paper-thin
- Small handful fresh cilantro leaves, chopped
- 1 tsp fine sea salt, plus more to taste
- 6 ice cubes
For the plate
- 1 medium camote (orange sweet potato), about 400 g
- 1 ear choclo (or 1 cup thawed frozen corn), boiled
- 4 tbsp cancha (toasted Andean corn kernels)
Equipment
- Sharp thin-bladed knife
- Fine-mesh sieve
- Blender or small food processor
- Chilled ceramic mixing bowl
Instructions
-
Boil the camote whole in salted water for 25 minutes, until a knife slips through easily. Cool, peel, and cut into 2 cm rounds. That sweetness is what balances the acid on the plate.
-
Soak the sliced red onion in ice water for 10 minutes. This softens the raw bite and keeps the rings crisp. Drain and pat dry before you use them.
-
Cube the fish into 2 cm pieces with a sharp knife. Larger cubes stay soft through the cure; smaller ones turn dense and chalky in the same time. Keep the fish cold right up until the moment you dress it.
-
Roll the limes on the counter under the palm of your hand to loosen the juice. Squeeze them by hand, never with a press. Squeezing too hard pulls bitter pith oil into the juice. You want about 180 ml of clean juice.
-
Make the leche de tigre. In a blender, combine 60 ml of the lime juice, the garlic, the ginger, half the ají limo, 1 tsp salt, and the six ice cubes. Add one spoonful of the fish for body. Blend 20 seconds, until the mixture goes pale and cloudy, then strain through the fine sieve into the chilled bowl. Stir in the rest of the lime juice.
-
Season the cubed fish with a pinch of salt and toss. Wait one minute. That first salt step pulls surface moisture out so the acid can grip. Skip it and the ceviche turns flabby.
-
Pour the cold leche de tigre over the fish and toss gently. Set a timer for 5 minutes. The edges of the fish will go opaque while the centre stays translucent.
-
Add the drained red onion, the rest of the ají limo finely chopped, and the cilantro. Toss once and taste. It should be sharp, salty, cold, and a little sweet from the leche de tigre.
-
Plate immediately. Arrange the ceviche in shallow bowls with camote on one side and choclo on the other. Scatter cancha over the top as you eat. Spoon the extra leche de tigre from the bottom of the bowl over the fish.
Notes
- Fish must be sashimi-grade or extremely fresh from a trusted fishmonger. Lima cooks use corvina; fluke, halibut, sea bass, or striped bass all work at home.
- Ají limo is hard to find outside Peru. Half a yellow habanero, seeded, gives a similar floral heat. Never substitute jalapeño; the flavour goes green and grassy.
- Persian limes are less aromatic than key limes. If you use them, add a scrape of zest to the leche de tigre for lift.
- Ceviche does not keep. Once dressed, eat it within 20 minutes. The fish goes on cooking in the acid and turns rubbery by the one-hour mark.
- A quick chile and lime reference for home cooks working outside Peru:
| Element | Peruvian original | Home substitute | What changes |
|---|---|---|---|
| Chile | Ají limo (fresh) | Half yellow habanero, seeded | Slightly less floral, similar heat |
| Chile | Ají amarillo (fresh) | Yellow bell + habanero blend | Loses signature perfume |
| Lime | Key lime | Persian lime plus zest | Less aromatic, add zest to compensate |
| Corn | Choclo (giant kernels) | Boiled sweet corn cob | Sweeter, less starchy bite |
| Toasted corn | Cancha serrana | Unsalted corn nuts | Similar crunch, adjust salt |
What to serve with
In Lima, ceviche shows up at lunch, never at dinner, and the drink beside it is a cold Cusqueña beer or a tall glass of chicha morada. A second plate of arroz con mariscos or a small pile of yuca frita often follows. Sunday lunch with the family, or a hot afternoon that needs cold food on the table.
