- Why is the meat chewy?
- You cut the slices the wrong way. Always slice against the grain to shorten muscle fibers.
P.F. Chang's Style Mongolian Beef
Despite the name, this is a Chinese-American classic. The key technique is 'velveting': coating meat in cornstarch. This protects the beef from drying out in the hot wok and thickens the sticky sweet-savory sauce that defines the dish.

Instructions
1
✓
Slice beef thinly against the grain. Toss with cornstarch to coat evenly.
Tip: Cornstarch protects meat from drying and thickens the sauce later.
2
✓
Heat oil in wok until smoking. Fry beef in batches (don't crowd!) until crispy edges form, then remove.
Tip: If you dump it all in, oil cools down and meat steams instead of searing.
3
✓
In the same pan, quickly sauté onion, garlic, and ginger.
Tip: Sauté only until fragrant; burnt garlic is bitter.
4
✓
Add soy sauce, water, and sugar. Boil until it starts to thicken.
Tip: Caramelizing sugar gives the sauce its shine and stickiness.
5
✓
Toss beef back in to coat with sauce. Sprinkle with green onions and serve.
Tip: The starch on the beef absorbs the sauce and thickens it instantly.
