I used Joule to cook short ribs ( choice) first at 133 degrees for 8 hours. The short ribs were tough-- not as I expected---. I then put them back sous vide at 147 degrees for an additional 8 hours but the ribs were not better and maybe even tougher.
( the recipe of 133 degrees for 8 hours was from serious eats)
Do I need to cook them longer and at what temp?
What am I missing?
