01 - Drain the tofu and press with a tofu press or clean towel and 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. Allow to marinate for 10 minutes.
03 - Mix cornstarch and rice flour in a separate bowl. Toss marinated tofu cubes in the mixture until evenly coated on all sides.
04 - Warm neutral oil in a large nonstick skillet over medium-high heat until hot.
05 - Place tofu cubes in a single layer in the skillet, working in batches if needed. Fry for 2 to 3 minutes per side, turning gently until all sides are golden and crisp, approximately 8 to 10 minutes total.
06 - Remove tofu from skillet and drain on paper towels. Serve immediately, garnished as desired.
