How to Make It
Set a large wok over high heat until it's very hot. Add the oil and swirl to coat the wok. When the oil is hot, add the garlic and scallions and stir-fry for 30 seconds. Add the pork, ginger and Hot Chile Paste and stir-fry for 30 seconds, pressing the meat and scallions against the side of the wok. Add the soy sauce and stir-fry for 30 seconds.
Add the tofu, broth and salt and bring to a vigorous boil, then lower the heat and simmer for 4 minutes. Add the cornstarch mixture and stir-fry over high heat until the sauce thickens and becomes clear, about 20 seconds. Transfer the tofu to a shallow bowl and serve hot, warm or at room temperature, with a small ladle.
