Roy's Blackened Ahi Quick Version: This is an abbreviated version of Roy Yamaguchi's signature recipe. The fresh ahi steaks are coated in a blackened seasoning mixture, lightly seared and served with a soy mustard sauce.
For a pretty presentation serve this in a bamboo steamer layer.
This traditional Hawaiian condiment is easy to make. Its traditionally served with Poke and sometimes with sushi too.
This recipe features the sweet Maui Onion. If you can't find them on the mainland then you can substitute the Vidalia or Texas or any sweet onion. This recipe is for large quantities but you can adjust it for home use.
