Cut the tofu into 1 cm thick rectangles, approximately 3 x 6 cm.
Mix together the sauce/marinade ingredients. Marinade the tofu in ¾ of the sauce for 1-2 minutes, turning to coat well while the air fryer preheats.
Bake the tofu in the air fryer at 200°C for 10 minutes.
While the tofu is baking, add the remaining ¼ of the marinade, coconut sugar, and cornstarch to a saucepan.
Cook over medium heat, whisking constantly until the sauce thickens and reduces.
Be careful not to burn it! If it thickens too much, add 2 tbsp of water and mix through. Remove from heat and set aside.
Take the tofu out of the air fryer and coat it in the glaze, ensuring all pieces are covered. Drizzle any remaining glaze over the tofu.
Return the tofu to the air fryer and bake again at 200°C for 5 minutes.
Sprinkle with sesame seeds and enjoy!
