Tuna Cubes with Citrus Soy, Chives, and Cucumber Recipe

This tuna salad is one of the most successful items I ever put on a menu. In 2½ years, I sold 62,000 orders! I think the public was trying to tell me something, and I’d like to pass it on to you. I’ve streamlined it a bit and lightened the flavors, but the idea of cubes of hand-cut tuna in a tangy, sweet, and savory dressing is still at the heart of this recipe. It’s the same flavor principle that works so well in beef tartare, but with more of an Asian accent.
