# Expert Insights:

01 -
  • The sauce hits every note: salty, sweet, tangy, and just spicy enough to make you reach for your water glass
  • It comes together faster than delivery would arrive, and you actually know what's in it
  • The beef stays impossibly tender because of a simple trick I learned from a chef friend
02 -
  • Crowding the pan while searing the beef will make it steam instead of brown, so work in batches if necessary
  • Have all ingredients prepped and the sauce mixed before you turn on the heat, stir-frying waits for no one
  • High heat is non-negotiable, that's what gives you that slightly smoky wok hei flavor restaurants achieve
03 -
  • Freeze the beef for 15 minutes before slicing, it'll cut cleanly into thin strips instead of shredding
  • If you don't have a wok, use your widest skillet and crank the heat as high as it goes
