- 2 teaspoons dry sherry
- 1 teaspoon soy sauce
- 1/2 cup plus 1 tablespoon cornstarch, divided
- 1 tablespoon water
- 1/4 teaspoon baking soda
For the sauce:
- 1/4 cup light brown sugar, packed
- 3/4 cup hot water
- 1/4 cup soy sauce
- 1 teaspoon dark soy sauce

- 8 dried red chilies
- 3 medium cloves garlic, finely chopped
- 4 scallions, white and green parts separated, cut on an angle into 2-inch-wide pieces
- 1 1/2 tablespoons cornstarch

Directions
Step 1 –In a large bowl, add the steak slices, 2 teaspoons of the vegetable oil, the sherry, 1 teaspoon of the soy sauce, 1 tablespoon of the cornstarch, 1 tablespoon of the water, and the baking soda and stir to combine.
Step 2 –Let the steak strips marinate at room temperature, about 1 hour. Set it aside.
Step 3 –In a small bowl, add the brown sugar and 3/4 cup of the hot water and stir until the sugar has dissolved.
Step 4 –Add the remaining 1/4 cup of soy sauce and 1 teaspoon of the dark soy sauce to the brown sugar mixture and stir to combine. Set it aside.
Step 5 –In a shallow bowl, add 1/2 cup of the cornstarch.
Step 6 –Dredge the marinated steak slices through cornstarch until they are thoroughly coated.
Step 7 –In a wok or large nonstick skillet over high heat, heat the remaining vegetable oil just until it starts to smoke.
Step 8 –In batches, add the coated steak slices in a single layer to the heated oil and cook until they reach an internal temperature of 135 degrees F and the coating is crusty, about 1 minute per side.
Step 9 –Transfer the cooked steak strips to a plate.
Step 10 –Turn off the heat. Reserve 1 tablespoon of the oil from the wok in a small bowl and discard the rest.
Step 11 –Carefully use a paper towel to wipe the wok clean.
Step 12 –In the same wok over medium-high heat, add the reserved oil, the ginger, and the dried chilies and cook, while stirring, about 15 seconds.
Step 13 –Add the garlic and the white scallions to the chili mixture and cook, while stirring, about 15 seconds.
Step 14 –Add the soy sauce mixture to the chili mixture and simmer, about 2 minutes.
Step 15 –In another small bowl, add the remaining 1 1/2 tablespoons of cornstarch and the remaining 2 tablespoons of water and stir to combine.
Step 16 –Slowly add the cornstarch slurry to the sauce mixture and stir to combine.
Step 17 –Add the cooked steak slices and the green scallions to the sauce mixture and cook, while tossing, until the scallions are wilted and there is hardly any sauce standing at the bottom of the wok, about 30 seconds.
Step 18 –Serve.
