Sauce
Place a small saucepan over medium heat. Add sesame oil, then lightly sauté ginger, garlic, and scallions for 1 minute. Add sriracha, chili sauce, soy, mirin and honey. Stir to combine. Remove from heat and set aside.
SNAPPER
Line a baking sheet with several layers of paper towels.
Slice snapper fillets into 1-inch pieces.
Whisk together whites and water and place in a mixing bowl. Whisk together flours, salt, and pepper in a mixing bowl.
Pour oil in a deep sided sauté pan or cast iron skillet over medium-high heat.
Dredge fish pieces, a few at a time in egg white mixture and then in flour mixture. Once oil reaches 350°F, place fish in pan and fry for 3 to 5 minutes until golden brown. Transfer to paper towel-lined baking sheet. Continue until all fish has been fried.
Fry the fish bones. This may take up to 5 to 7 minutes per side (trust me this is a show stopper).
Toss fish pieces with chili sauce and pile into one side of fish bones. Place fried fish bones on platter and pile on fried snapper pieces.
