I haven’t been able to find frozen pearl onions in Calgary for years now.  But to peel each one with a paring knife is a big pain.  But here is a method to cut down the pain.  You could also buy a few bags  at the Farmers market in the fall  when they are cheaper. Peel using the method below then freeze on a cookie sheet. When frozen put  in a ziplock  bag for future use in the freezer .

• Boil water.
• Plunge the little buggers in said boiling water for two minutes.
• Drain them, and pour them into a bowl of ice water.
• After you’ve let them sit there until they’re cool enough to handle, drain them again, then get to work.
• One quick slice at the bulb end, a quick squeeze at the other end, and those little babies pop right out of their skins.
