01 - Drain and press tofu with a tofu press or wrapped in a clean kitchen towel under a heavy object for at least 10 minutes to remove excess moisture. Cut into ¾-inch cubes.
02 - Combine soy sauce, sesame oil, garlic powder, and black pepper in a bowl. Add tofu cubes and gently toss to coat. Let stand for 10 minutes to marinate.
03 - In a separate bowl, mix cornstarch and rice or all-purpose flour. Coat marinated tofu cubes evenly in the flour mixture.
04 - Preheat neutral oil in a large nonstick skillet over medium-high heat until shimmering.
05 - Place tofu cubes in a single layer, working in batches if necessary. Fry each side for 2 to 3 minutes until golden and crispy on all sides, about 8 to 10 minutes total.
06 - Remove tofu from the skillet and drain on paper towels. Serve immediately as a snack, salad topping, or stir-fry addition.
