Directions

1. Heat oven to 375 degrees. Tie each short rib with kitchen string, and season with salt and pepper. Heat oil in a large Dutch oven over medium-high heat, and brown short ribs on each side. Remove short ribs, and cook carrots, celery, onions, and shallots until onions and shallots turn golden brown, 5 to 10 minutes. Add tomato paste and flour, and cook 2 to 3 minutes.
2. Return short ribs to the pot, and deglaze with port and red wine. Cook until wine is reduced by 2/3. To make the bouquet garni, bunch rosemary, parsley, thyme, and bay leaves together, and tie the bundle with kitchen string. Add bouquet garni, garlic, and stock to pot. Bring to a boil, and cover. Transfer to oven, and cook until meat is fork-tender, about 3 hours.
3. Transfer short ribs to large platter. Strain sauce through a fine sieve or cheesecloth into a medium-size saucepan. Reduce sauce over medium heat until it thickens to a gravylike consistency. Adjust seasoning to taste, spoon sauce over short ribs, and serve.
