04 - 1/2 cup hoisin sauce
05 - 4 cloves garlic, minced

# How to Make It:

04 - Pour the sauce mixture over the beef and toss to coat evenly.

06 - Stir well before serving. Serve hot over steamed rice or with steamed vegetables.

# Expert Advice:

01 -
  • The sauce develops this impossibly rich depth that tastes like it simmered all day even though the hands on time is literally minutes
  • Your house will smell like a trustworthy takeout place but with ingredients you can actually pronounce
02 -
  • Cornstarch is your friend if you want restaurant thickness, just whisk 2 tablespoons into cold water and stir it in during the last 30 minutes
  • The sauce will separate slightly as it cooks, which is normal and actually a good sign that all those flavors are developing properly
03 -
  • Partially freeze the flank steak for 30 minutes before slicing and you'll get those paper-thin cuts without struggling
  • Let the beef come to room temperature while you make the sauce for more even cooking
