1 1/2 pounds broccoli with florets, cut into 3/4 inch pieces, and stalks trimmed, peeled, and cut on an angle into 1/4 inch thick slices
1/4 tsp sugar
Preparation steps
Whisk broth, sherry, soy sauce, sesame oil, cornstarch, and chili-garlic sauce together in a bowl. Combine garlic, pepper flakes, and 1 tsp oil in another small bowl.
Heat 1 Tbsp oil in a large, heavy skillet over medium-high heat until it begins to smoke. Add broccoli and sprinkle with sugar. Cook, stirring frequently, for 8-10 minutes until broccoli is well browned.
Push broccoli to the edges of the skillet clearing a spot in the middle. Add the contents of the small bowl (pepper-oil-garlic) to the center, mashing for 20-30 seconds with a spoon or spatula until garlic is fragrant, then mix together with the broccoli. Add the broth/sherry mixture and cook, stirring constantly, until the sauce is thickened, about 1 minute.
