Hi all, and especially Violet! It's looking like I'm going to have a HUGE crop of oranges this year and we don't do marmalade at our house. I've been researching canning orange juice or making orange juice concentrate for the freezer and haven't come up with anything that seems safe yet. The Ball book has a recipe for canned grapefruit juice but not orange. Any ideas why?   I also found the following recipe and was wondering if it is safe:   http://myspringhillgarden.com/?p=207
