Begin by slicing off any excess roots hanging off the end while still leaving the root in place
Slice off the very top of the stem. Be careful not to cut off too much, only enough so that you expose the very tops of all the garlic cloves from within the skins.
Remove most of the papery skin from the outside of the bulb, except for the very first layer- leave that to help hold the cloves in place.
Place the bulb onto a sheet of foil, root side down.
Drizzle with olive oil and pull all the ends of the foil up to the top wrapping the garlic bulb tightly and securing the top shut by pressing together to seal.
Bake for 1 hour in a small oven safe pan.
Remove from the oven and cool. Use immediately or store in the refrigerator.
