Place a piece of aluminum foil in each muffin hole for your garlic bulbs.
Cut the top off the garlic so you can see the cloves and place into the muffin tin.
Drizzle a little olive oil over each garlic head. (about 1 to 1 1/2 teaspoons)
Cover the aluminum foil over each bulb and and bake for 30-35 minutes (test to see if the garlic feels squishy) Once it's squishy, it's done.
Remove from the oven and allow them to cool.
Once cooled you can remove the garlic cloves from the bulb with a fork or squeeze out if cool enough to handle.
You will want to peel off the outside of the husk to expose the garlic cloves. You may need to cut the top to expose any that were not cut to get them out of the skin.
If you are not going to use all the garlic at once, store them in a air tight freezer safe container and freeze until you are ready to use. Lay the container (and if a bag lay flat) so it's easy to remove a clove at a time.
Be sure your mark and date the package to help identify later.
