Recipe for Roy's Signature Blackened Ahi with Soy Mustard Sauce. This is one of the most popular appetizers from Chef Roy Yamaguchi’s restaurants.
- Soy-Mustard Sauce:
- 1/4 cup mustard powder, preferably Coleman's®
- 2 tablespoons hot water
- 2 tablespoons rice wine vinegar
- 1/4 cup soy sauce
- Blackening Spice:
- 1 1/2 tablespoons paprika
- 1/2 tablespoon cayenne pepper
- 1/2 tablespoon pure chile powder
- 1/4 tablespoon freshly ground white pepper
- 1/2 tablespoon ground sandalwood (optional)
- 8 ounces ahi tuna filet, about 2 inches thick and 5 inches long
- 2 tablespoons olive oil
- 3/4 cup warm beurre blanc sauce (see recipe links below)
- 2 to 3 tablespoons pink pickled ginger
- 1/2 tablespoon black sesame seeds, toasted
- 1 ounce daikon sprouts
- Serves 4 as an Appetizer
- To prepare the mustard sauce, mix the mustard powder and hot water together in a cup to form a paste. Let sit for a few minutes to allow the flavor and heat to develop. Add the vinegar and soy sauce, mix together, and pass through a fine mesh sieve into a bowl. Cover and refrigerate for at least 1 hour to allow the flavors to develop.
- Prepare the beurre blanc and warm in the top of a double boiler.
- Mix all of the blackening spice ingredients together on a plate. Dredge the ahi in the spice mixture on all sides.
- Heat the olive oil in a skillet over high heat and sear the ahi for 15 to 30 seconds on each side for rare, 1 minutes on each side for medium-rare, or to the desired doneness. Remove the ahi and cut into 20 thin slices.
- For each serving arrange 5 slices of ahi in a fan, pinwheel, or cross shape on the plate. Spoon or drizzle a little of the soy mustard sauce around the tuna, and then spoon or drizzle the beurre blanc around. To garnish, arrange a small mound of the pickled ginger next to the fish and top with the daikon sprouts. Sprinkle the sesame seeds over the soy-mustard sauce.
