Every February thru April I drive to Phoenix, Arizona and pick organic lemons, grapefruit and tangerines. I juice them and load my car with around 40 gallons of various juice and drive home to Montana as fast as I can. I visit my grandson while I am there too. I canned some grapefruit juice and it turned out ok. Of course it was consumed within a 3 month period so I don't know if it stays fresh and doesn't brown in the jar.
I usually freeze the lemon juice for use in recipes etc...but I would rather can it if possible. Any thoughts or experience with this?
