Finish preparation before heating
Cut ingredients into evenly sized pieces and arrange them in cooking order. Mix the sauce and stir any starch slurry immediately before using it. Have the serving dish ready. The active cooking window is too short for measuring sauces or peeling garlic.
Work with your equipment
A wok is useful, but a roomy skillet can work on a home stove. Preheat appropriately for its material and avoid overheating nonstick coatings. Use a cooking oil suited to the heat. You do not need theatrical flames or a smoking kitchen to cook a good meal.
Cook in sensible batches
Too much cold food drops pan temperature and encourages steaming. Cook proteins or tofu separately when helpful, then remove them. Start firm vegetables before delicate ones; garlic can enter late enough to avoid burning. Return the protein to complete cooking with the sauce.
Sauce lightly and serve promptly
Add sauce around the ingredients and toss until it coats rather than floods the pan. Add a little water if starch makes it too tight. Finish with herbs or a small amount of toasted sesame oil if appropriate. Verify animal proteins have reached their safe temperature; thin slices still need proper cooking.
Your next kitchen exercise
Stir-fry two batches of vegetables with the same sauce, one crowded and one in smaller batches. Compare browning and the amount of liquid left in the pan.
