# Expert Tips:

01 -
  • It's ready faster than you can order takeout, yet tastes like you spent your whole evening on it.
  • The sauce coats every piece of beef and vegetable so perfectly you won't need much rice to feel satisfied.
  • You control the heat, so whether you like a gentle warmth or genuine fire on your tongue, this adapts to you.
02 -
  • Don't overcrowd the pan when searing beef or it will steam instead of brown—work in two batches if needed.
  • High heat is your friend here; a medium flame will give you beef that's gray and sad instead of caramelized and delicious.
03 -
  • If you want even more color and char on your beef, pat it dry with a paper towel before it hits the pan.
  • A wok or large skillet matters more than you'd think—the shape and heat distribution change how everything cooks, and I notice the difference every time.
