Pat dry the tofu, cut into cubes, and toss with 2 tbsp cornstarch.
Mix stir-fry sauce ingredients in a bowl and set aside.
Heat 1/4 cup oil in a pan and fry tofu until golden. Drain on paper towels.
In the same pan, sauté shallot, garlic, ginger, scallion whites, and chili peppers until fragrant.
Add the sauce and bring to a light simmer.
Mix 1 tsp cornstarch with 1 tbsp water, stir into sauce, and simmer until thickened.
