Choy Sum With Oyster Sauce - cooking recipe

Ingredients

1 tablespoon vegetable oil, divided
1 pinch salt
1 pinch white sugar
1 pound choy sum
1/2 teaspoon minced garlic
3 tablespoons water, divided, or as needed
1 tablespoon oyster sauce
1 teaspoon Shaoxing wine
1/2 teaspoon soy sauce
1/4 teaspoon white sugar
1/8 teaspoon monosodium glutamate (MSG)
1 teaspoon cornstarch, or more to taste

Preparation

Bring a large saucepan of water, 1 teaspoon vegetable oil, 1 pinch salt, and 1 pinch sugar to a boil. Add choy sum and cook for 30 seconds. Drain, pressing gently to squeeze out excess water. Place choy sum on a serving dish.
Heat remaining 2 teaspoons oil in a wok or skillet over high heat. Cook and stir garlic until fragrant, about 30 seconds. Add 2 tablespoons water, oyster sauce, Shaoxing wine, soy sauce, 1/4 teaspoon sugar, and monosodium glutamate; bring to a boil.
Mix remaining 1 tablespoon water and cornstarch together in a small bowl. Pour into the wok; cook and stir until sauce thickens, about 1 minute. Pour sauce over the choy sum.
