- In a large ovenproof pan, brown the shanks on all sides in 30 ml (2 tablespoons) oil. Season with salt and pepper. Set the shanks aside on a plate.
- Remove the fat from the pan. Brown the fennel and onion in the remaining oil. Add the garlic and cook for 1 minute. Deglaze with the Pernod and reduce until almost dry.
