I’m glad you boys didn’t cut your nuts off with your frisbee. (We benighted Apple device users can see flickr slideshows, btw, so the link back to the original set is useful.) Apparently one way of dehusking the nuts is to drill a hole in a piece of hardboard and bash the nuts through with a hammer, rather like a child’s pegboard toy. Sounds like fun to me! I wonder whether it’s easier to get the kernel out if you leave the dehusked nut to dry before attempting extraction.
