# Expert Suggestions:

01 -
  • This recipe lets you channel a restaurant kitchen at home—there&aposs a secret crispiness you can never quite find in takeout.
  • It comes together in a flash but tastes like you fussed for hours.
02 -
  • Crowding the beef in the pan won&apost give you that coveted crisp—you need high heat and breathing room!
  • Stirring the sauce before pouring it in prevents any clumps and keeps the glaze perfectly silky.
03 -
  • Always pat the beef dry before marinating so the cornstarch coats evenly—too much moisture means no crisp.
  • A wok gives best results, but a wide, heavy skillet works too as long as it&aposs hot enough.
