Prepare Tuna: Begin by ensuring your workspace is clean and sanitized. Rinse your hands thoroughly and place the sushi-grade tuna on a cutting board. Using a sharp knife, slice the tuna into uniform half-inch cubes, ensuring you achieve a beautiful, fresh texture that will melt in your mouth. This step should take about 5 minutes.

Make Dressing: In a medium mixing bowl, combine the grated ginger, lime juice, tamari or soy sauce, sesame oil, honey, and chili flakes. Using a whisk, blend the ingredients together for around 3 minutes until the dressing is well mixed and smooth.

Marinate Tuna: Gently fold the cubed tuna into the dressing, making sure each piece is evenly coated with the flavorful mixture. Allow the tuna to marinate for about 10 minutes at room temperature.

Shape Tartare: Retrieve a chilled plate and a ring mold or spoon to help shape your Tuna Tartare. Carefully spoon the marinated tuna mixture into the mold, pressing it down gently for a neat presentation. This step should take about 2 minutes.

Garnish and Serve: Top the Tuna Tartare with thinly sliced scallions and a sprinkle of white sesame seeds for an added pop of freshness. Serve immediately with crispy wonton chips or cucumber slices.
