How to Make It
In a small bowl, whisk the soy sauce with the sugar, red pepper, garlic, sesame oil, ginger and sesame seeds.
Slice the tofu crosswise into 8 thin slabs. Dry the tofu with paper towels, pressing until no moisture remains.
In a large skillet, heat 1/4 inch of oil until shimmering. Add the tofu and cook over moderate heat, turning once, until browned and crisp, about 8 minutes per side. Drain on paper towels. Spoon the sauce over the fried tofu and sprinkle with the scallion. Serve with steamed rice.
