1 tspsea salt flakes, divided

Equipment

A little context

Rooted in the coastal and Andean traditions of Peru, ceviche relies on the 'leche de tigre' (tiger's milk) curing process. Traditional recipes sometimes add a touch of sugar or use processed corn; here, we honor the authentic flavor profile by using naturally sweet, whole Peruvian choclo and omitting any refined sweeteners. We strictly avoid seed oils often found in commercial ají pastes, ensuring the fat source is pure, cold-pressed extra-virgin olive oil.

Method

01
Prepare the Choclo
Bring a large pot of salted water to a rolling boil. Add the choclo kernels and blanch for exactly 3 minutes. The kernels should remain firm and crunchy, not soft. Drain immediately and plunge into an ice bath to stop cooking. Drain thoroughly.
02
Make the Aji Emulsion
In a blender, combine the aji amarillo paste, minced garlic, cilantro stems, and 2 tablespoons of the lime juice. Blend until smooth. Slowly drizzle in half of the extra-virgin olive oil while blending to create a loose, emulsified sauce. Season with a pinch of salt.
03
Cure the Trout
Place the wild trout cubes in a non-reactive glass bowl. Pour the remaining lime juice over the fish. Gently toss to ensure every piece is coated. Let sit at room temperature for 10 minutes. The fish will turn from translucent to opaque white on the edges, indicating the acid has denatured the proteins.
04
Prepare the Onions
While the fish cures, soak the sliced red onion in ice water with a squeeze of lime for 10 minutes to mellow the sulfur compounds. Drain well and pat dry with a clean kitchen towel.
05
Combine and Dress
Add the blanched choclo, drained red onion, and the aji emulsion to the bowl with the cured trout. Gently fold everything together. Drizzle with the remaining extra-virgin olive oil and toss once more. The oil should coat the ingredients, not pool at the bottom.
06
Rest and Serve
Let the mixture rest for 5 minutes to allow the flavors to meld. Fold in the fresh cilantro leaves and torn mint. Serve immediately on chilled plates. Do not let it sit for more than 20 minutes, or the fish will become too firm and the corn will lose its crunch.

Pro tips

✦Sourcing is critical: Ensure your trout is labeled 'wild-caught' and has been flash-frozen at -20°C (0°F) for at least 7 days to ensure it is safe for raw consumption.
✦The corn must be Peruvian Choclo if possible; its large, starchy kernels provide the necessary texture contrast. If unavailable, use frozen organic sweet corn but do not overcook it.
✦Do not use bottled lime juice; the citric acid in bottled juice lacks the complex terpenes of fresh fruit and often contains preservatives that alter the flavor.
✦Taste the 'leche de tigre' (the marinade) before adding the fish; it should be sharp but balanced by the oil. Adjust salt only at the end.

Substitutions

wild-caught rainbow trout → wild-caught Arctic char or steelhead trout (Both have a similar fat profile and firm texture suitable for acid curing.)
Peruvian choclo → fresh sweet corn kernels (Texture will be softer; blanch for only 1 minute.)
aji amarillo paste → yellow bell pepper blended with a pinch of cayenne and turmeric (Will lack the specific fruity heat of aji, but provides the color and mild spice.)

Storage

Best consumed immediately. If necessary, store in an airtight glass container in the refrigerator for up to 24 hours. The fish will continue to cure and become firmer; the texture is best within the first 2 hours.

What to serve with it

Sparkling water with fresh lime and a sprig of mint
Unsweetened hibiscus tea (agua de jamaica)
Grilled asparagus or roasted sweet potato wedges
A small side of sliced avocado with sea salt

FAQ

Why can't I use regular corn?+

Regular sweet corn is often too soft and lacks the distinct starchy crunch of Peruvian choclo, which is essential for the textural balance of this dish.

Is this recipe spicy?+

It has a mild, fruity heat from the aji amarillo. If you are very sensitive to heat, remove the seeds from the fresh aji peppers if making your own paste, or reduce the amount to 1 tablespoon.
