Remove the tofu from the package and place on a plate. Put something heavy on top of it, and leave it for an hour.

Cut the tofu into bite-sized pieces, then toss with 1 tbsp of cornstarch.

Combine all the sauce ingredients in a small mason jar, and shake well to combine.

In a frying pan over medium-high heat, heat up a couple tablespoons of neutral oil, like canola. Add the tofu to it, and fry until golden brown, about 5-10 minutes.

Add the sauce and stir well. It will thicken very quickly. Toss the tofu well in the sauce to coat.

Serve atop a bed of rice, and garnish with sesame seeds and chopped green onion.
