Ingredients
  

Toast + Toppings
  • 2 slices Gluten-free sourdough
  • 1 Avocado
  • 1 tablespoon Capers
  • ½ Lime zest
  • Avocado oil reserved from frying the shallots
Tuna Tartare
  • ½ lb Sushi-grade tuna yellowfin, bluefin, or ahi
  • 1½ teaspoon Yuzu kosho
  • ½ teaspoon Sesame oil
Crispy Shallots
  • 1 tablespoon Shallot thinly sliced on mandoline
  • ¼ cup Avocado oil for frying
  • Kosher salt

Equipment

  • Mandoline
  • Medium nonstick frying pan
  • Mixing Bowls

Method
 

Prep the Veg & Tuna
  1. Finely chop the capers.
  2. Dice the avocado into ¼" cubes (tip: press through a cooling rack over a bowl).
  3. Cut the tuna along the grain into ¼" slices, then dice into small cubes.
Make the Tuna Tartare
  1. In a nonreactive bowl, combine diced tuna, 1 teaspoon yuzu kosho, sesame oil, and half the chopped capers. Mix gently.
  2. Taste and adjust. Add the remaining ½ teaspoon yuzu kosho for more heat, or additional capers for salt.
Crispy Shallots + Toast
  1. Heat ¼ cup avocado oil in a pan over medium until it reaches 350–400°F.
  2. Add sliced shallots and fry until golden brown. Remove to a paper towel–lined plate and season with kosher salt.
  3. Pour off all but 2 tablespoon of oil, then toast gluten-free sourdough slices until golden and crisp on both sides.
Assemble
  1. Spoon diced avocado over the toast. Sprinkle with some crispy shallots.
  2. Top with a layer of tuna tartare. Finish with lime zest and more shallots if you're feeling bold.

Notes

Storage: This is an assemble-to-order dish. Raw tuna doesn't hold, so keep the diced tuna chilled and mix it with the yuzu kosho just before serving; toast the bread and fry the shallots right before you build the toast.
