# Expert Tips:

01 -
  • Five ingredients create a sauce that tastes like it simmered all day
  • The beef becomes impossibly tender without any fancy techniques
  • Your slow cooker does absolutely everything while you go about your life
02 -
  • Slicing the beef against the grain is not optional—look for the lines running through the meat and cut perpendicular to them
  • Resist the urge to lift the lid during cooking, every time you do you add 15-20 minutes to the cooking time
  • The sauce will look thin at first but thickens beautifully as it cooks down with the beef juices
03 -
  • Freeze the beef for 30 minutes before slicing—it makes cutting those thin strips so much easier and more precise
  • Double the sauce if you love things extra saucy, because leftover rice coated in this sauce is basically the best lunch ever
