Add cornstarch in a small bowl. Then whisk egg with Tikka Masala in another small bowl. Finally, add in panko flakes or bread crumbs into a third small bowl.
Carefully remove the tofu block from its package. Slice into cubes.
Coat each tofu cube first in the cornstarch bowl, then egg, then panko flakes or bread crumbs.
Add vegetable oil into skillet, heat on medium-high fire. The oil will be ready when bubbles form around the handle of a wooden chopstick or spoon when placed in the oil.
Place all the tofu cubes into the skillet. When one side browns, flip it over to another side. Repeat until nicely browned. Remove from skillet and drain on paper towel. Serve hot with sesame-soy dipping sauce.
