Place cloves in an oven-safe pan and drizzle with olive oil & sprinkle with salt

Cover tightly with foil and bake for 30 mins at 400 degrees. It can also be done in a pan on the stove, but keep the heat from getting too hot. Since it's usually the hottest part of the summer when I'm putting up garlic, I like to do this on the grill. Foil-covered foil pans, or an iron skillet (covered with foil) work great. Just remember to use indirect heat and shake them around frequently so they don't get too brown.
