Cut the tofu into bite-sized cubes.

Place the tofu on a kitchen towel to remove excess moisture.

Coat the tofu with frying flour using a plastic bag for even coverage.

Pan-fry the tofu in a skillet with a moderate amount of oil until golden and crispy.

Prepare the sauce by mixing ketchup, sugar, corn syrup, soy sauce, and minced garlic in a bowl.

Remove the fried tofu and place it on a kitchen towel to drain excess oil.

Heat the sauce in a pan until it starts to bubble, then turn off the heat.

Add the tofu to the pan with the sauce and mix until evenly coated.
