What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Choose water spinach with slender, tender stems—thick ones are often fibrous and woody.
- 2After washing, shake the water spinach well or spin it dry so the wok stays hot and the dish doesn't steam.
- 3Have all ingredients prepped and within arm's reach; the entire stir-fry takes under 3 minutes.
- 4Use a well-seasoned wok or a heavy skillet to maintain high heat for that smoky wok hei flavor.
- 5If you can't find white pepper, use freshly cracked black pepper for a sharper, aromatic finish.
- 6Serve immediately—water spinach continues to cook and will turn limp and soggy as it sits.
