Preheat oven or toaster oven to 400 degrees.Take whole garlic bulb and slice off the top third of the bulb. Use paring knife to gently create a little space between each clove. Drizzle about a tbsp of olive oil over the top including the top part you cut off. Return sliced part to the top and wrap tightly with two sheets of tin foil. Place on baking sheet and roast in oven for 45 minutes. Remove from oven and allow it to cool enough to handle.
