Prepare the tofu by pressing it to get rid as much liquid out of the tofu.
Slice your tofu into bite-size pieces, about an inch on both sides.
On a large plate, combine cornstarch, salt, and black pepper. Coat the tofu slices with the cornstarch mixture.
In a frying pan or skillet, heat enough cooking oil. Pan-fry the coated tofu in batches. Fry all the sides until golden brown and crispy on the edges.
Let’s make our sweet and sour orange sauce while frying tofu. In a bowl, combine a quarter cup of water, whole orange juice, or about a half cup, orange zest, soy sauce, brown sugar, sesame oil, ginger paste, and two tablespoons of cornstarch. Mix until well combined.
Saute the minced garlic in two tablespoons of cooking oil for a minute or two or until fragrant. You can use the same skillet where you fried the tofu.
Turn the heat on low. Pour the sweet and sour orange sauce, stir and let it thicken, and form a glaze. Turn off the heat. Sprinkle sesame seeds and green onions. Serve with rice.
