FAQ

Can I cook the tuna more if I don't like it rare?

Yes, sear for 1-2 minutes per side for medium-rare, but be careful not to overcook as tuna becomes dry and tough quickly.

What if I can't find mirin?

Substitute with 1 tablespoon dry sherry mixed with 1/2 teaspoon sugar, or use rice wine vinegar with a pinch of sugar.

How long will leftover dipping sauce keep?

The sauce keeps in the refrigerator for up to 1 week in an airtight container and pairs well with other grilled fish or vegetables.
