Thanks Constance, that's a great idea for freezing the garlic.
I always use garlic when cooking and, for the first time, my husband has planted two rows of the stuff. He has begun pulling it and is drying it in his shed/workshop. Boy, does it smell garlicky (sic?) in there and I'm glad it's not being dried in the attached garage or, horrors, in my laundry room. I'm definitely going to try your idea, especially with the smaller heads and/or any that might begin to sprout. We understand it keeps well, just hanging around, but your method should be super for excess so it doesn't go to waste.
