TO ROAST THE GARLIC: Preheat oven to 400 degrees F. Cut the top off the garlic bulb to expose the cloves. Place the cut bulb on a large piece of aluminum foil and drizzle with olive oil and salt. Gather the edges of the foil and press together to completely encapsulate the garlic. Bake for 30 minutes or until the cloves are completely soft. Unwrap the garlic bulb and squeeze the roasted garlic out of each clove into a bowl.
