Too many people spend way too long extending and protracting the process of peeling a clove of garlic. There’s no need to roll it in a rubber sheath nor strip at it with a paring knife. Life’s too short to waste time on such unnecessary inefficiency. Three steps, five to ten seconds, your garlic is peeled.
1) Place your knife flat upon the garlic.

2) Press down firmly, but do not strike the blade.

3) Grasp the peel at the sprot end in one hand and the garlic at the root end with the other.

They come apart effortlessly. If you have to peel a lot of garlic, perform each step on all cloves before proceeding to the next step. Only press down on one clove (or clove group, if a couple or three cloves are stuck together as one) at a time. If you’re trying to mash multiple groupings, none of them come apart as well or as quickly as if you were to do each separately in succession.
Also, if you need a great deal of garlic for any particular purpose (~1 bulb or more), place the bulb on your cutting board root side up and press down on it as you would to peel a single clove of garlic. The cloves will come apart from the bulb much more quickly than if you were to try to pull them all off individually.
