1. In a bowl, whisk together lime juice, lemon juice, ají amarillo paste, soy sauce, sesame oil, neutral oil, grated ginger, garlic, and rice vinegar until smooth; season lightly with salt and pepper. Taste and adjust acidity or heat as desired. 2. Arrange thin slices of fish on a chilled serving platter in a single layer. Scatter the thinly sliced red onion and chile over the fish. 3. Spoon the citrus-aji marinade evenly over the fish so each slice is lightly coated; let sit 1–2 minutes for the flavors to mingle but not "cook" the fish fully. 4. Sprinkle chopped cilantro, toasted sesame seeds, and cancha (or crispy shallots) over the top. Serve immediately, garnishing with extra lime wedges if desired.
