Rice Cracker Crusted Tuna With Spicy Citrus Sauce

Preparation

1. For the Spicy Citrus Sauce

   1. Step 1

      For the spicy citrus sauce: Place bonito flakes in a small bowl and cover with 3 tablespoons hot water. Allow to sit for 10 minutes, then strain through a fine-meshed sieve, squeezing out as much liquid as possible.

   2. Step 2

      Transfer liquid to a blender. Add egg yolk, lime juice, orange juice, sriracha and salt. Pulse to mix. With blender running at medium-high speed, slowly drizzle in the oil until mixture is thickened. Transfer to a covered container and refrigerate until ready to serve.

   3. Step 3

      For the tuna: Pour oil to a depth of three inches in a heavy, deep saucepan and heat to 400 degrees on a deep-fat thermometer. Meanwhile, combine egg whites and cornstarch in a shallow bowl, and whisk until smooth. Coat tuna pieces in mixture, then dredge in rice-cracker crumbs, making sure surface is covered.

   4. Step 4

      Carefully transfer tuna to hot oil, turning once, until deep golden brown, about 15 seconds a side; tuna should remain rare in center. Remove carefully and drain on paper towels. Cut tuna crosswise into 1-inch pieces, and arrange decoratively on serving plates. Stir scallions into citrus sauce, and spoon onto plates. Serve immediately.
