Preheat the oven to 325 degrees. Melt 1 tablespoon margarine in large ovenproof pot over medium heat. Sprinkle ribs with salt and pepper.

Add onions and sauté until brown about 6 minutes. Add parsnips and cook about 6 minutes. Mix in garlic, then rosemary. Add wine and broth and bring to a boil.
Return ribs and any juices to pot trying to arrange in a single layer. Bring to a simmer and cover and place in the oven. Braise until ribs are very tender about 2 ½ hours.

Using tongs, transfer ribs to a clean bowl. Remove fat from pan juices. Boil juices until just beginning to thicken about 10 minutes. Mix 1 tablespoon margarine and flour in small bowl to smooth paste. Whisk into juices in pot and simmer until thickened enough to coast a spoon about 5 more minutes. Season gravy with salt and pepper. Return ribs to pot and serve with gravy.

In a separate pot, bring pareve milk, margarine and rosemary to simmer.
