Spicy Tuna Filling

This filling is a staple for quick hand rolls, rice bowls, or toasted sandwiches. It relies on the interplay between the creaminess of the mayo and the sharp bite of the chili paste.

Before you start

Dry tuna is better tuna.

If the tuna is too wet, the filling will turn into a soup. Press the fish against a fine-mesh sieve or paper towels until it is completely drained.

Ingredients

What goes in.

  • 1 can (5 oz)tuna in water, drained well
  • 3 tbspJapanese mayonnaise
  • 1-2 tspSriracha
  • 1/2 tsptoasted sesame oil
  • 1 stalkscallion, finely sliced
  • 1/4 tsptogarashi (optional)
The key technique

Use a fork to control the texture

Don't mash the tuna into a paste. Use the tines of a fork to gently break the larger chunks into smaller, individual strands so the sauce coats every piece without turning it into mush.

Step by step

The method.

  1. Drain the tuna

    Empty the can into a sieve and press firmly with the back of a spoon to remove all excess liquid.

  2. Flake the fish

    Transfer the tuna to a bowl and use a fork to break up the larger chunks into a loose, shredded consistency.

  3. Emulsify the sauce

    Add the mayonnaise, Sriracha, and sesame oil to the bowl. Fold gently until the mixture is uniform and coats the fish strands.

  4. Finish

    Fold in the scallions and top with a pinch of togarashi if you want extra heat and texture.

Variations

Other turns to take.

Crunchy style

Add 1 tablespoon of finely diced cucumber or tempura flakes for an added snap.

Citrus profile

Squeeze a tiny drop of fresh lime juice into the mixture to brighten the heavy fats of the mayo.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Use Japanese mayonnaise, like Kewpie, because it is made with egg yolks rather than whole eggs, creating a thicker, richer consistency.

Tip

Let the mixture sit in the refrigerator for 15 minutes before serving so the flavors settle into the tuna.

Tip

If you find the heat level too intense, add a tiny pinch of sugar to round out the bite of the Sriracha.

Questions

The ones that keep coming up.

Can I use tuna in oil?

You can, but the filling will be much richer. If you use oil-packed tuna, drain it partially, but not as aggressively as the water-packed variety.

How long will this last?

Keep it in an airtight container in the coldest part of your refrigerator for up to 24 hours.
