2cbeef brothor could do 1/2 cup red wine and 1.5 c. broth for deeper flavors.
Instructions
Preheat the oven to 400 F. Pour vegetable oil into a preheated frying pan and fry the shanks on both sides for 5 minutes over high heat. Then transfer to a plate. Over medium heat, fry the onions, carrots and celery, stirring.
After 5 minutes, add flour and mix thoroughly. Add tomato paste, salt, spices and broth. Bring to a boil and cook for another 3 minutes, stirring.
Transfer the beef shins to a Dutch oven or roasting pan. Pour in the sauce, add bay leaf and garlic. Cover with a lid and roast in the oven for 120 minutes.
If there is not enough liquid, you can add a little water or broth so they are submerged. Remove when the meat is tender enough to shred with 2 forks. Serve with the sauce covering it.
** If you want the sauce thicker at the end you can remove the meat, set Dutch Oven on stovetop over medium high heat. Once bubbling, allow to reduce and thicken. Or whisk together 1 tbsp cornstarch with some of the hot liquid, stir that in to thicken to your liking.
