Cut the tofu into bite-sized pieces.
Coat the tofu evenly with starch after removing excess moisture.
Pour enough cooking oil into a pan and fry the tofu until golden brown.
Mix together soy sauce, sugar, gochujang (Korean red chili paste), minced garlic, and oligosaccharide to make the sauce.
Add the sauce to the fried tofu and toss well to coat evenly.
Serve the finished tofu on a plate and sprinkle with sesame seeds and chopped green onions.
