# Expert Advice:

01 -
  • The contrast between crispy beef and that sticky tangy sauce is absolutely addictive
  • Ready in 40 minutes but tastes like it came from a restaurant kitchen
  • Customizable heat level means everyone at the table stays happy
02 -
  • Double frying the beef (30 seconds first round, 2 minutes second round) makes it stay crispy longer even after tossing in sauce
  • Slice your beef when it's slightly frozen—it's so much easier to get thin, even strips that way
03 -
  • Cut all your beef strips to similar thickness so they cook at the same rate
  • Pat the beef dry with paper towels before coating—excess moisture prevents proper crisping
