❓ Frequently Asked Questions

Q: What cut of beef is best for stir-fry?
A: Flank steak, sirloin, ribeye, or skirt steak are excellent choices because they cook quickly and stay tender when sliced thinly against the grain.

Q: Can I make this ahead of time?
A: Yes. Slice and marinate the beef and prepare the sauce up to 24 hours in advance. Cook just before serving for the best texture.
