Setting the boiled broccoli florets in ice-cold water for a few minutes will help to retain a bright green color after cooking and make them crunchier.
Cooking stir-fry dishes must be quick. DO NOT overcook, or the dish will be soggy. Once the shrimp is just cooked through, add broccoli and sauce, and give a quick toss for about 1 to 2 minutes.
The sauce should be light and not sticky. Give the sauce a little bit of stir before pouring it into the wok to prevent getting clumps in the final dish.
