Note from Ricardo The tofu can be cooked in an air fryer. Add 2 tbsp (30 ml) vegetable oil to the bowl of tofu and mix well. Add the cornstarch and toss to coat the tofu well. Season with salt and pepper. Spread the tofu out in the basket of the air fryer. Cook for 15 minutes at 400°F (200°C). Stir the tofu and continue to cook for 5 minutes or until very crispy. Remove the basket from the air fryer and remove the grill. Pour in the remaining soy sauce mixture and stir to coat the tofu well. Continue to cook for 3 minutes or until the sauce is thick and syrupy. Add the sesame seeds and mix well.
