1-Step 1: Prep the onion and fish Start by soaking the 1/2 red onion in salt for 15 minutes. This softens its sharp bite and helps keep the flavor clean instead of harsh. After that, rinse it well and set it aside. While the onion rests, cut the fish fillet into 2 cm cubes and reserve the thinner pieces for the leche de tigre. If you are using a very delicate fish like sole, keep the cubes neat so they hold their shape when mixed.

2-Step 2: Season the ceviche base Place the fish cubes in a bowl and mix them with the finely chopped ají or rocoto, the sliced onion, salt, and pepper. Stir gently so the fish stays intact. Let the mixture rest for a short time while you prepare the marinade. This brief rest helps the seasoning begin to soak into the fish and onion. If you prefer a milder result, use less chili and add more onion for crunch. For a stronger Peruvian-style bite, use a little more ají or rocoto. The beauty of Ceviche Peruano Con Leche De Tigre is that you can make it suit your own taste without losing its classic character.

3-Step 3: Make the leche de tigre For the Leche de Tigre, squeeze the limes fresh and keep the juice with ice until you are ready to blend. Cold juice helps the fish stay firm and gives you a cleaner result. Add the 40 g pieces of fish, 30 g onion, garlic cloves, ají or rocoto, celery, ginger, salt, sugar, cilantro stems, and lime juice to a blender. Blend until the ingredients are broken into small pieces. Next, strain the mixture through a fine sieve or strainer, pressing the solids well to extract as much juice as possible. This liquid is your leche de tigre, and it should smell bright, fresh, and lightly spicy. Taste it and adjust with a little more salt, pepper, or sugar if needed. If the limes taste too sharp, a small pinch of sugar helps smooth the acidity without making it sweet. Fresh lime juice is the soul of this marinade. If you want that classic punchy flavor, do not use bottled juice.

4-Step 4: Combine and briefly marinate Pour the leche de tigre over the fish mixture and toss gently. The fish should be coated well, but do not let it sit too long. A short marination is all you need, because the lime begins to change the texture quickly. For classic Peruvian ceviche, serve it right away while the fish is still tender and bright. Keep in mind that ceviche is not a long-marinate dish. If it sits too long, the fish can become tough or bitter. That is why timing matters so much here. This is also why many home cooks prepare every part in advance and combine everything just before serving.

5-Step 5: Plate and serve immediately Arrange the ceviche on a serving plate with the cooked sweet potatoes, cilantro leaves, and cooked corn. Spoon a little extra leche de tigre over the top if you like more sauce. The sweet potato adds natural sweetness, the corn gives body, and the cilantro brings freshness to the final plate. Serve right away for the best texture and flavor. If you want a more festive table, add extra onion on top and place a few lime wedges on the side. The result is a colorful, lively plate that feels both simple and special.
