Instructions

1. Step 1: Chill the tuna on a cutting board; pat dry with paper towels. Ensure your knife is very sharp and clean.
2. Step 2: Make the dipping sauce by whisking together soy sauce, lime juice, sesame oil, and grated ginger in a small bowl; set aside.
3. Step 3: Slice the tuna into 1/8–1/4 inch (3–6 mm) thick sashimi slices by cutting across the grain in smooth, single strokes; wipe the knife between cuts to keep slices clean.
4. Step 4: Arrange slices on a chilled plate in a single layer or slight overlap. Sprinkle a pinch of sea salt and the sliced scallions over the fish.
5. Step 5: Place a small dollop of wasabi on the side of the plate (or serve in a small dish) and add pickled ginger to the platter.
6. Step 6: Garnish with a light dusting of toasted sesame seeds if using. Serve immediately with the soy-lime dipping sauce and chilled beverages.
