Recipe Information
Ingredients
- 300 grams sushi-grade tuna
- 4 tablespoons lime juice
- 2 tablespoons lemon juice
- 0.25 cup red onion
- 1 small cucumber
- 1 medium ripe avocado
- 1 small jalapeño pepper
- 0.25 cup fresh cilantro
- 1 tablespoon extra virgin olive oil
- 0.5 teaspoon sea salt
- 0.25 teaspoon black pepper
Instructions
Dice the sushi-grade tuna into small, uniform cubes (about 1 cm or 1/2 inch). Place into a non-reactive bowl (glass or stainless steel).
Add the lime juice and lemon juice to the bowl with the tuna. Stir gently to coat the fish evenly with the citrus juices. Cover the bowl with plastic wrap and let it sit in the refrigerator for 10-15 minutes. This will lightly 'cook' the tuna with the acidity of the citrus.
While the tuna marinates, finely dice the red onion and cucumber. Chop the avocado into small cubes. Mince the jalapeño pepper (remove seeds and ribs if you prefer less heat). Roughly chop the fresh cilantro.
Remove the tuna from the refrigerator and add the prepared red onion, cucumber, avocado, jalapeño, and cilantro.
Drizzle the olive oil over the mixture and season with sea salt and black pepper. Gently toss everything together to ensure it’s well mixed without breaking up the avocado.
Taste and adjust seasoning with additional salt, pepper, or lime juice if needed.
Serve immediately in chilled bowls or plates. Optionally, garnish with extra cilantro leaves or a few slices of lime on the side.
