When I roast garlic just for bread-application, I chop a little off the top to expose the cloves, but leave it all together, in the paper. Fold it up in aluminum foil with a squirt of olive oil, and when it’s done it pops right out of the paper in a marvelous gooey mess.

Yes, that’s what I do with a whole head of garlic. It also fills the house with the most amazing and tantalizing odor!
