A sharp, clean Nikkei tiradito built around bonito. A dressing of lime, shoyu, ginger, and sesame touches the fish only at serving time, with creamy avocado and ají limo sharpening the contrast. It arrives cold, glossy, and light enough that a second plate feels like the natural next course.
Turn what you find into an experience you can actually bring to your kitchen.
Keep the bonito well chilled until slicing and use only fish whose handling for raw consumption you can verify; lime juice does not make poorly handled fish safe. Pat it dry, remove bones and excessively fibrous dark portions, then slice it on a slight angle into pieces about 3 mm / 1/8 inch thick with a very sharp slicing knife. Arrange them in a single layer on chilled plates and refrigerate again while making the dressing.
Finely grate the ginger and finely chop most of the ají limo. In a bowl combine the lime juice, soy sauce, mirin, sesame oil, ginger, chopped chili, most of the cilantro, and salt for 30 seconds, until glossy and homogeneous. Taste it: citrus and salt should lead, with only a faint sweetness and toasted sesame aroma at the finish; keep chilled until serving.
Slice the avocado neatly and cut the scallions into very thin rounds. Finely chop the remaining ají limo and have the sesame seeds and remaining cilantro ready. Do this last so the avocado keeps its color and the scallions stay fresh.
Take the plates from the refrigerator and spoon the Nikkei dressing over the bonito immediately before serving, using enough to coat the slices without leaving them swimming. Add the avocado, scallions, remaining ají limo, remaining cilantro, and sesame seeds. Take it straight to the table: the ideal result keeps the fish firm and the dressing bright. And that’s it—between the shoyu, lime, and cool avocado, the final piece tends to disappear before anyone remembers this was supposed to be a starter.
