# Expert Advice:

01 -
  • Everything cooks fast enough that you can actually relax after dinner instead of collapsing into bed.
  • The sesame and hoisin give it that takeout richness without the grease or the wait.
  • Leftovers taste even better the next day when the noodles soak up more sauce overnight.
02 -
  • Do not crowd the wok when you cook the beef or it will steam instead of sear. Work in batches if you need to.
  • Rinse the noodles after boiling or they will stick together in a clump and refuse to separate when you toss them in the sauce.
  • Have everything prepped and ready before you start cooking because once that wok gets hot, things move fast and there is no time to chop garlic mid-stir-fry.
03 -
  • Freeze the beef for fifteen minutes before slicing so it firms up and you can get thinner, cleaner cuts.
  • Use the highest heat your stove can manage. Stir-frying is all about that quick sear and smoky flavor you only get from serious heat.
  • Taste the sauce before adding it to the wok and adjust the balance. Some brands of hoisin or oyster sauce are sweeter or saltier than others.
