I've decided to dehydrate veggies this year to help stock my pantry. I've dehydrated apples, pears, peaches and celery for several years with good results, but I haven't ever tried yellow squash, zucchini, broccoli, or beans. I know several people on this forum dehydrate so I'm asking here. Do I need to blanche the veggies first or do I just cut them up? Does the squash work best if the seeds are cut out? Anything else I need to know?
