- 4 pounds large, meaty oxtail pieces, patted dry
- Coarse salt
- Freshly ground pepper
- 2 tablespoons safflower or other neutral-tasting oil
- 1 cup all-purpose flour
- 1/2 cup red wine
- 1 bunch watercress, trimmed
Season oxtail generously with salt and pepper. In a large pan, heat oil over medium-high heat. Place flour in a shallow pie pan; season with salt and pepper. Dredge oxtail in flour mixture until coated all over, shaking off excess flour.
Working in batches, sear oxtail until well browned on all sides, about 15 minutes. Remove oxtail and set aside. Place oxtail in Sport graniteware pots. Add wine and enough water to cover one quarter of the oxtail. Place in the Solavore Sport to cook. After 3 hours, add additional 2 cups water if necessary. Continue cooking until meat is tender and pulls away from bone, 3 hours more.
Remove oxtail and set aside. Pour cooking liquid into a fat separator. Allow fat to rise to top. Pour defatted cooking liquid back into pot. Cook until reduced and thickened, about 15-30 minutes. Return oxtail topot and stir in watercress. Cook until oxtail is heated through, about 5 minutes.
Serve oxtail either on the bone or with meat removed from bone and transferred to a shallow dish. Pour reduced cooking liquid and watercress mixture over meat and serve immediately.
