This isn’t the spicy tuna you find in most sushi joints. Instead of using the ubiquitous Sriracha mayo combo, I season the tartare with my Spicy Korean Mustard Vinaigrette. The result is lighter and more vibrant and clean tasting. It also goes very well with Lotus Root Chips, you can either spoon a little on the delicate chips or serve the chips on the side. As always, when consuming raw fish, make sure it’s fresh and of the highest quality.


  • 8 ounces/226grams sashimi-quality tuna, diced

  • Heaping 1/3 cup/75grams finely diced seedless cucumber

  • 2 tablespoons thinly sliced scallions (spring onions) or fresh chives

  • 2 tablespoons Spicy Korean Mustard Vinaigrette

  • 4 teaspoons toasted sesame oil

  • 2 teaspoons roasted sesame seeds, plus more for serving

  • 2 teaspoons black sesame seeds, plus more for serving
