I've had bumper crops of both over the years. Before I had a dehydrator, I would freeze them and they always became slimy after thawing. If you are able to have crispy celery after you freeze, I'd love to know your secret. When something like celery or watermelon are frozen, the freezing process compromises the cell structure and when thawed, the cells explode, causing the water to be released and making them soggy. I haven't found a way to combat this natural process with these foods when frozen. One of the main reasons I use veg like celery and peppers is for their texture contrast in my foods. When you dehydrate, it doesn't destroy the cell structure and when rehydrating, they maintain their integrity better. If you have freezing tips, though, please share. I'm always ready to learn a new technique!
