That requires you to have two bowls of the same size, and that's two more dishes that have to be washed.

Obviously you don't have to use bowls, an old pickle/sauce jar works too. You don't really have to wash it either, just put a drop of soap in it, bit of water, shake for 2 seconds, and rinse.

So including cleanup you're talking 20 seconds

The two bowls thing is a notorious hoax. No one has ever gotten it to work.

or stick it in a microwave for twenty seconds, it takes twice as long but you will avoid all that bruising.

Bruising? You're going to be cooking it, which will break every cell in it.

Not only is garlic not always cooked, but even when cooking, it makes a difference if you slice it vs mincing it. The more you damage it before cooking, the sharper the flavor.
