I find peeling garlic in the normal manner very tedious. I use this trick to speed it up.
Put your unpeeled garlic clove(s) in a microwave oven and heat for a few seconds. How long depends on how much garlic you have and how powerful your microwave is. I usually set it for 10 seconds.
The garlic gets hot and sort of pops its skin, making it easy to shuck off.
