I like to gently peel the paper, trim the tip, make a pouch with aluminum foil, drizzle olive oil (less than 1 tsp pur large bulb) and a pinch of salt on top before wrapping it up. I place these into a muffin tin, bake at 350 for about 45 minutes, longer for more mellow and sweeter garlic. You can bake at 400 for 30 minutes, but I prefer low and slow. 4 cloves is about right for 1/2 of butter, but since I'm Greek, I usually double that.
