In a large heavy bottom pot over medium heat, add in celery root, parsnip root, whole milk, garlic and thyme. Bring to a simmer and reduce heat. Simmer 5 to 7 minutes or until fork tender. Strain, reserving liquid. Discard thyme bundle. Place vegetables in food processor and pulse, adding reserved liquid as necessary to desired consistency, pulse to desired texture. Add butter and salt and pepper to taste, and pulse. Garnish with bacon and fried onions. Serve with reduced broth from Short Ribs.
Preheat oven to 350 degrees F.
In a large Dutch oven, over medium-high heat, cook bacon to render fat. Remove bacon and reserve for another use. Season ribs with salt and pepper. Sear all sides of ribs, in batches, ends included, and then remove. Add in vegetables, cook for 5 minutes, add flour and spices, cook for 3 minutes longer and deglaze pan with red wine. Put the ribs back into pot and add stock to cover 3/4 of the way up the ribs. Cover and cook in oven for 1 hour 30 minutes to 1 hour 45 minutes or until fork tender. Remove ribs to a baking dish and brush with Balsamic Glaze, cover with foil and keep warm in a preheated 250 degrees F oven. Strain and reduce broth by a third. (Reserve broth for another use.)
In a small pot over medium heat, combine all ingredients. Whisk occasionally and reduce by one third.
