Magga - I just kept cooking the apples down until the consistency was what I wanted. It is just like we would buy in the grocery.
Sharon, I live an hour or so from a place called Roscoe Village.
http://www.roscoevillage.com/ It is a "restored" old town, with shoppes and blacksmith etc. Touristy. But, they have a thing each year called Apple Butter Stirrin' Festival.
http://www.roscoevillage.com/p... They make apple butter then in the big kettles over open fires. I think it is just for show - they don't sell it. Probably to many food laws or something against selling it cooked out in the open and not in controlled conditions. The festival promotional flyers etc. all say Smell the apple butter, none talk about buying or tasting it.
