I've tried all KINDS of pecan shelling methods and gadgets!
And I can tell you two things for SURE:
1) Boiling the pecans for ten minutes will definitely make them easier to shell. In my opinion, they were easiest to shell if I got busy on 'em while they were still warm. I boiled small batches, scooped 'em out with a strainer and shelled 'em as soon as I could handle without burning my fingers.
2) Those antics are all in my past however, since I obtained what surely is the best nut cracker to be had, bar none--- the Texas Native Inertia Nutcracker. Here's the website:
http://www.inertianutcracker.com/ I got lucky and found mine on Craig's List, but have seen them on Ebay also.
Amazingly simple design, extremely well-built and heavy duty for years of service. I don a pair of those Mr. Clean rubber-coated work gloves to improve my grip and avoid blisters, then I can crank out enough beautifully shelled pecans to make several pies AND a fat goody bag of shelled pecans for a neighbor, in just a couple of hours! My inertia nutcracker puts 'em all to shame and is the way to go if you shell 'em yourself and want to do it FAST and as easily as possible (and you don't have 150 bucks for that hand-crank beauty!).
I remember a third thing I can tell you, pertaining to boiling pecans:
3) When you forget and leave the giant covered vessel on high until it boils dry, then you suddenly remember and rush in to find it tetering around and making strange sounds on the burner, do not--I repeat--
DO NOT put the seething time bomb into the sink and run water on it!!! Yep, I are a college gradgiate, but clearly I never took physics---or maybe it's cuz I'm AN AGGIE, but all I can tell ya is the instant water hit the lid on that pot there was the loudest explosion sound I've ever been next to. Luckily it was actually the sound of an IMplosion, or I'd probably be dead and my giant spaghetti-sauce pot wouldn't be lookin like a crunched up beer can. I could not BELIEVE that gigantic stainless steel pot was crumpled instantly! But I beliveve it now sooooooo BEWARE!!! HaHa!
Good luck with those nuts!
