What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Slice beef against the grain for tender strips that won't toughen during cooking.
- 2Pat bell peppers dry after washing to prevent excess steam in the wok.
- 3Let the wok get smoking hot before adding oil to achieve a proper sear on the beef.
- 4Cook the beef in a single layer and resist stirring for the first minute to develop a brown crust.
- 5Stir the sauce slurry just before pouring, as cornstarch settles quickly.
- 6Taste a piece of bell pepper before finishing — it should be tender-crisp with a slight bite.
- 7Leftovers keep in the fridge for up to 3 days; reheat in a hot wok to revive crispness.
