1. Make your sauce. Combine soy sauce, maple syrup, rice vinegar, water, minced garlic, and grated ginger in a small saucepan. Set it over heat, bring it to a simmer and let it cook for about 10 minutes. 2. When the sauce is about finished simmering, stir some cold water and cornstarch together in a small cup or bowl, then add it to the sauce. Once it starts simmering again it should thicken up quickly. Now take it off of the burner. 3. Stir in some sesame oil.
4. Dredge tofu cubes in cornstarch to coat, then fry them in the oil for a few minutes, until crispy.
5. When the tofu and sauce are both done cooking, combine them in the skillet. 6. Pour the sauce over the tofu, give it a few flips, and let it cook until everything is hot and the sauce is bubbly!
7. Top with sesame seeds and scallions, then serve over rice.
