I want to make the Chili Sauce recipe in the Ball Blue Book but due to health issues cannot get to it soon. Can I freeze the tomatoes and make this another time? What kind of prep work should I do before freezing? I would appreciate any help 
and for me "later" is often so far away that I stick them in the freezer. Easy to skin later too. Just drop the whole, frozen tomatoes into a pot of water. Skins slide right off with just a tad of rubbing.Wash them, and put them in a ZipLoc, burp the air out of it, and can them later! It works well!
