In a shallow plate whisk together the flour, salt and pepper
Dredge the short ribs through the flour mixture, making sure all sides are covered in flour
In a large Dutch oven, heat the olive oil over medium-high heat
Add the ribs, only half of them at a time, do not over crowd them and sear them on all sides, about 3 to 4 min per side until browned. Repeat with remaining ribs.
Remove the ribs from the pot and set aside.
