We use quite a bit of shallots at the restaurant. But it's not to the extent that we need a commercial peeler. I don't like the peeled shallots our vegetable supplier has as they were soaked in water and flavours are lost. I found something interesting on the internet that helped the peeling process.
I took 2 metal containers and put some shallots into it. Then the two containers are shook vigoursly for about 30 seconds. Some of the shallots and completely peeled but for some, some of the skin is still stuck. But the skin could be easily peeled off. This simple process is saving us lots of time and tears.
