ROOT VEGETABLE PUREE

Steps:

• Preheat the oven to 400 degrees. Brush the carrots, parsnips, turnip and sweet potato with the olive oil and place the vegetables on a large baking sheet. Roast until tender, about 30-45 minutes, turning frequently. Set aside to cool.
• Peel the sweet potato. Finely chop all of the roasted vegetables and transfer to a large saucepan.
• Add the celery root, mace, nutmeg, thyme, broth and Sherry vinegar. Bring to a boil and simmer over medium heat for 15 minutes. Transfer to a blender or food processor and puree until smooth. Add the salt and pepper. Serve with the veal shanks.
