Peruvian Ceviche (The Authentic Method)

Forget everything you think you know about ceviche! True Peruvian ceviche 'cooks' the fish in just 2 minutes using the power of lime acidity, a technique honed by generations of Lima cooks – not the 20-minute (or overnight!) marinades often found elsewhere. **Why This Works:** The rapid 'cooking' relies on incredibly fresh fish and a high concentration of citric acid from Peruvian limes. The short contact time preserves the delicate texture of the fish while denaturing proteins, creating the characteristic ceviche texture.

Equipment

Sharp knife

Fine-mesh sieve

Instructions

Ensure your fish is *extremely* fresh – sushi-grade is best. This is non-negotiable for the 2-minute cook time.
Cut the Corvina/Flounder into 1/2-inch cubes. Place in a non-reactive bowl (glass or ceramic).
Pour the freshly squeezed lime juice over the fish, ensuring all pieces are submerged. Gently stir to coat.
Add the thinly sliced red onion, minced aji amarillo (or paste), chopped cilantro, salt, and pepper to the bowl.
Gently stir again. Let the fish sit in the lime juice for *exactly* 2 minutes. Do not exceed this time.
While the fish is 'cooking', prepare the Leche de Tigre: In a blender, combine the reserved lime juice, fish scraps, minced garlic, minced ginger, and salt. Blend until smooth. Strain through a fine-mesh sieve to remove solids.
After 2 minutes, the fish should be opaque and firm. Taste and adjust seasoning if needed.
To serve, arrange a lettuce leaf on each plate. Spoon the ceviche onto the lettuce. Garnish with sliced sweet potato and Peruvian corn.
Drizzle a tablespoon of Leche de Tigre over each serving. Serve immediately – within 5 minutes of preparation is crucial.
