Jane, I assume that arum seeds are close enough to arisaemas to use the same method. Here's what I do. Find your least favorite kitchen blender. Fill the jar half way with water, add seeds. Pulse it a few times until the seed skins are floating on the surface, and the seeds sink to the bottom. Pour the contents through a strainer, and spread the solid remains on a paper towel. Let this dry out overnight. Scuff it up a bit, and the clean seeds will roll right off. Using this technique, I have never worried about using gloves, with no irritation at all to my hands. Believe me, I have gone through the red, swollen hands routine more than once, most memorably in a hotel in Yunnan when I didn't know any better. This technique works because the seeds are light enough and their coats are hard enough so they bounce off of the blender blades. I've never seen so much as a nick in the seeds after processing. Don't worry about contaminating your blender, either. Anything bad will rinse off, no scrubbing required. --Roy NW of Boston Lots of wild Arisaema triphyllum and Arisaema stewardsonii seeds ripening out in our woods.
