I read the comments on Amazon about how great these things are. Everyone complains about what a pain it is to peel garlic otherwise, trying to pull all the little papery shreds off with their fingernails.
Hello? All you have to do is lay your knife blade flat on a clove of garlic, give it a good thump with the heel of your hand and, voilà, the skin pops right off.
Same principle, but one less object to clean (assuming you're going to be using the knife anyway).
If you want to be really gadgety, you can get a garlic mandoline, too. I'm including this video mainly for the Wisconsin accent. My homeland.
Some people don't want to touch garlic. They don't want the scent of garlic on their fingers. This puzzles me.
