In this recipe from the folks at Every Day with Rachael Ray, garlic goes from firm and sharp to creamy and sweet when roasted.
If using more than 1 bulb (head) of garlic, place the bulbs in a glass baking dish and cover with tin foil. Bake for the same amount of time.
Cut 1⁄4 inch off the top of a whole blub (head). Place the bulb on foil, drizzle with olive oil, and wrap tightly. Bake at 400 degrees for 45 minutes until tender. Squeeze the garlic "paste" out, and use in your favorite way.
