Ingredients

Scale
  • 1 lb sushi-grade Ahi Tuna, finely diced
  • 1 large ripe avocado, mashed for mousse
  • 2 tablespoons soy sauce or tamari
  • 1 tablespoon sesame oil
  • 1 teaspoon fresh ginger, grated
  • 1 teaspoon sriracha (adjust to your spice preference)
  • 1/2 lime, juiced
  • 1 green onion, thinly sliced
  • 1 teaspoon toasted sesame seeds for garnish
  • Taro chips or wonton crisps, for serving

Instructions

  1. Prepare the tuna: Place the finely diced sushi-grade Ahi Tuna in a chilled bowl.
  2. Make the spicy marinade: In a small bowl, whisk together the soy sauce, sesame oil, grated ginger, sriracha, and lime juice.
  3. Combine: Pour the marinade over the diced tuna. Gently fold in the sliced green onion. Do not overmix; you want the tuna pieces to hold their shape.
  4. Prepare the avocado mousse: In a separate bowl, mash the avocado until completely smooth. Season lightly with salt and pepper if desired.
  5. Assemble: To serve, place a ring mold on your serving plate. Spoon a layer of the avocado mousse into the bottom of the mold. Gently press down.
  6. Top the mousse layer with a generous portion of the marinated tuna tartare. Press lightly to set the shape.
  7. Carefully remove the ring mold. Garnish the top of the tuna with toasted sesame seeds.
  8. Serve immediately with crispy taro chips or wonton crisps for scooping.

Notes

  • Use only the freshest, sushi-grade tuna from a trusted source for this raw preparation.
  • For a Napoleon tower presentation, layer the avocado mousse and tuna in alternating layers inside a ring mold before serving.
  • If you prefer a milder flavor, reduce the sriracha or omit it entirely for a simple, fresh tuna tartare.
