BG- fess up how to do the apple butter in the crockpot!

I wanted to try and learn how to can this year, but I figured I'll go easy and just freeze stuff. A guy at work convinced me to just freeze the tomatoes I'm about to pick out of my landlady's garden (she left a bunch behind and told me to 'have at em') which the guy told me how to do. Next year, if I'm staying put, I will canning a shot. I would love to make my own jam but I have no clue on how to. I still have to get that Animal, Veg, Min book I keep hearing about...

anddddd you people in Mass have Concord grapes growing EVERYWHERE! I smell them when I'm riding! All over the place...if I only could find time to make jam...
