01 - Press the tofu for at least 15 minutes to remove excess moisture, then cut into 3/4 inch cubes.
02 - In a mixing bowl, toss tofu cubes with cornstarch and salt until fully coated.
03 - Heat vegetable oil in a large skillet or wok over medium-high heat. Arrange tofu in a single layer and fry, turning occasionally, until uniformly golden and crisp (about 8–10 minutes). Transfer to a paper towel-lined plate.
04 - In a separate bowl, whisk together orange juice, soy sauce, maple syrup, rice vinegar, tomato paste, garlic, ginger, orange zest, and sesame oil.
05 - Pour the orange sauce into the skillet and bring to a gentle simmer over medium heat.
06 - Stir in the cornstarch slurry; cook while stirring until the sauce is glossy and thickened, approximately 2–3 minutes.
07 - Return crispy tofu to the pan and fold gently to coat all pieces in the sauce. Cook for an additional 2 minutes until heated through.
08 - Distribute onto plates and garnish with sliced green onions, sesame seeds, and optional orange zest. Serve hot.
