Step 1

In a liquid measuring cup, add all the ingredients for the stir fry sauce. Slice the scallions and set aside. Allow the ginger, garlic, and Szechuan peppercorns to soak while you slice the beef.

Step 2

Lay the flat iron steak on a cutting board. Cut the beef against the grain into thin slivers. Then toss the beef strips with the corn starch.

Step 3

Set a wok (or XL skillet) over high heat. Add both oils. When the oil starts to smoke, carefully toss in the beef strips and Szechuan chiles. Quickly move them around the wok to stir fry the beef on both sides.

Step 4

Once the beef is mostly cooked (2-4 minutes) stir in the sauce. Allow the sauce to simmer and thicken. Once it reaches your desired consistency, turn off the heat. Serve warm, sprinkled with chopped scallions and sesame seeds.
