Overview

How to prepare Lima-style ceviche with camote and choclo

In Lima, a familiar ceviche plate pairs cleanly cut fish with lime juice, red onion and ají limo. The sweet potato and choclo served alongside are not just decoration: their soft sweetness and starch balance the sharp, freshly assembled fish dressing. This is a practical classic-style preparation rather than a claim that every Lima kitchen follows a single formula.

Cutting the fish into even cubes allows the lime and seasonings to contact each surface at about the same rate. The onion is added late so it retains its crispness. Ají limo is a specifically Peruvian aromatic chili; ordinary generic hot pepper cannot be assumed to reproduce its perfume.

Start with the cooked accompaniments, then cool them before handling the raw fish. Work with a cold bowl, squeeze the lime gently without grinding its rind, and serve the ceviche straight after a brief toss. Acidity changes the appearance of fish proteins but never substitutes for safe fish sourcing.

Ingredients

Cooked accompaniments

400 g sweet potato (camote), peeled, cut into thick discs
320 g Peruvian choclo kernels, removed from cob
1400 ml water, for boiling both accompaniments

Ceviche

700 g firm white fish suitable for raw consumption, boneless, skinless, cold, cut into 2 cm cubes
140 ml fresh lime juice, strained
160 g red onion, thinly sliced
12 g ají limo, seeded, finely chopped
10 g cilantro, leaves chopped
5 g fine salt

Method

Cook the accompaniments.Put 400 g sweet potato and 320 g choclo in a saucepan with all 1400 ml water. Bring to a steady simmer and cook until both are tender, lifting out the choclo earlier if ready. A thin knife slides into the sweet potato and the corn kernels yield when bitten.
Cool the cooked sides.Drain the sweet potato and choclo, spread on a clean tray and cool for 10 minutes before arranging on four plates. The cooked accompaniments are no longer steaming. Refrigerate cooked sides if not assembling promptly.
Prepare chilled vegetables.Cut the 160 g red onion into thin plumes and finely chop 12 g ají limo and 10 g cilantro; keep everything cold and separate from the fish board. The onion pieces are fine and springy rather than crushed.
Cut and season the fish.Cut 700 g chilled fish into even 2 cm cubes on a separate sanitised board, transfer to a cold bowl, and fold through 5 g salt and the chopped ají. The cubes retain clean edges and are evenly speckled with chili. Fish stays at 4 °C or colder until final assembly.
Finish quickly with citrus.Pour over 140 ml freshly strained lime juice and add the red onion and cilantro; toss gently for 1 minute and divide among the plated camote and choclo. A light citrus dressing gathers beneath intact fish cubes. Serve immediately; lime does not reliably destroy pathogens.

Practical

Practical guidance

Cooked camote can be cut into neat discs that stand beside the fish rather than underneath it. Leave a little room for the lime dressing to collect in the plate, so the corn retains some distinct texture. Assemble four equal portions; the recipe is scaled as a complete lunch. Bring the cooked corn and sweet potato to a safe cool serving temperature before they approach the chilled raw-fish bowl. You can prepare these cooked accompaniments earlier, cool them promptly in shallow containers, and refrigerate them. Only mix raw fish, chopped onion and lime when you intend to eat. If the finish tastes too sharply acidic, check the actual measured lime volume and the amount of liquid that has drained from the fish rather than adding a sweet ingredient not included here. Avoid squeezing the lime rind hard, which can release bitterness.

Control points

Fish cubes crumbleThey may have been stirred forcefully or cut too small; use clean 2 cm cuts and fold lightly.
Corn remains toughThe kernels need more simmering; taste one before draining the cooking water.

Allergens and food safety

Contains raw fish. Lime changes texture without making raw seafood microbiologically safe. Refrigerate fish at 4 °C or below; avoid raw seafood for pregnant people, children, older adults and immunocompromised diners.
