I couldn't stop thinking about the shake-peel so I just gave it a whirl.
two full bulbs pf garlic later, my first impressions of the shake-peel go like this:
I'm shocked this works at all.
lots of cloves are unpeeled after multiple shaking sessions.
deeper bowls could make a difference.
I have to clean the bowls afterward because garlic juice is coating the entire inside of the bowl.
The garlic cloves are very bruised and damaged after the shaking.
prep work of cutting off the root end and the top of the cloves makes them much more likely to be peeled by the end of the shaking.
maybe if I get better at this or I have better tools, this will save time and effort; right now it's more difficult and disrupts my chill kitchen flow with some pretty frantic shaking, but I could see it getting easier and less disruptive as I get used to it.
definitely an interesting suggestion and something I'll try to improve on, thanks for bringing it up.
