Instructions

1. Pat tuna steaks dry and season lightly with sea salt and black pepper. Set a heavy skillet or cast-iron pan over high heat until very hot.
2. Add 1 tsp (5 ml) neutral oil and sear each tuna steak 20–30 seconds per side for a rare center (longer if you prefer medium-rare). The goal is a thin cooked crust with a cool, raw interior. Immediately transfer to a plate and refrigerate 5–10 minutes to firm for easy slicing.
3. Meanwhile whisk together soy sauce, rice vinegar, lime juice, mirin, aji amarillo paste, toasted sesame oil, grated ginger, grated garlic, and chopped green onion until integrated. Taste and adjust acidity, salt, or heat.
4. Slice the chilled tuna crosswise into very thin slices. Arrange on a chilled serving plate.
5. Spoon the dressing over the sliced tuna, scatter toasted sesame seeds, add cucumber slices and microgreens or cilantro. Finish with a light drizzle of sesame oil if desired and serve immediately with steamed rice or as part of a Nikkei tasting.
