Tuna tartare may sound fancy, but it’s really easy to make! Combine fresh sushi grade tuna, cucumber, avocado, scallions, and the sauce ingredients and serve chilled with chips.
Finely dice the tuna in small cubes the size of a dice.
In a small bowl, mix the soy sauce or tamari, sesame oil, and sriracha. Adjust the amount of sriracha depending on how spicy you like it.
In a larger bowl, gently mix the diced tuna, scallions, and ginger if using, and cucumber. Pour the sauce mixture over the ingredients and gently toss to coat evenly. At this point you can refrigerate until ready to eat.
Add the avocado just before serving, this keeps it from browning.
To serve, place the tartar in a bowl and serve immediately. If I'm feeling fancy, I'll use a ring mold to shape the tartare on the plates like I did for these shrimp stacks. Garnish with scallions.
