Notes
This recipe works well in the Instant Pot. Use the saute feature to braise the meat. The Instant Pot needs at least 1 cup of liquid so add in 1/2 cup of beef broth. Use the manual high pressure function and set it to high. Cook the short ribs for 45 minutes, do a 10 minute natural release.Instead of short ribs you can also use chuck roast cut into 2 inch pieces.
