The recipe

Ingredients

Contains: fish, sesame (auto-detected from the ingredients and method; we can miss things, so check labels)

Directions

Prepare the tuna

  1. Grind equal parts of the five-spice mix in a coffee grinder.

  2. Portion the ahi tuna into 4-ounce portions and season with salt.

  3. Rub the tuna with the five-spice mix to coat completely.

Sear and slice

  1. Heat a non-stick pan and add 2 tablespoons of vegetable oil. Once the oil is hot, add the tuna to the pan.

  2. Sear each side of the tuna for 30 seconds.

  3. After all sides are seared, place the fish on a paper-towel-lined plate to absorb excess oil.

  4. Slice the tuna into one-quarter-inch thick pieces.

Make the tartar and vinaigrette

  1. In a stainless steel bowl, mix the mango, red pepper, cucumber, red onion, cilantro, lemon oil or olive oil, salt, and white pepper.

  2. In a blender, add the avocado, wasabi powder, minced shallot, seasoned rice wine vinegar, and lemon juice; blend until smooth.

  3. While the blender is running, slowly add sesame oil and olive oil, adjusting seasoning as needed.

  4. Pour the vinaigrette into a container and keep cold until ready to serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Ahi tuna
Forms the main protein; a quick hard sear browns the outside while the center stays rare.
Avocado
Adds creamy body and richness to the vinaigrette, letting it emulsify smoothly.
Mango
Adds natural sweetness and juiciness that balance the spiced tuna and wasabi heat.
Wasabi powder
Provides sharp, pungent heat that gives the vinaigrette its characteristic kick.
Rice wine vinegar
Adds gentle acidity that brightens the vinaigrette and cuts its richness.
Olive oil
Supplies fat that carries flavor and gives the vinaigrette a smooth, emulsified texture.

The step that matters

Searing the tuna for 30 seconds per side. Tuna cooks fast, so a short sear in a very hot pan browns the surface while keeping the center raw. Longer cooking turns the fish dry and gray through the middle.

Flavor stand-ins for the white pepper

Fit is the average pairing score against pepper, star anise, fennel, mango, cucumber, onion, lemon. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
