i don't mean the canning part, i mean the actual making of the apple butter. i am looking to avoid the hours of standing at a stove, and i would rather try apple butter production in a pressure cooker, rather than a slow-cooker.
I don't think I'd try it. My mother blew up a pressure cooker when I was a kid cooking apples. If I remember correctly, they foamed up, clogged up the vent and the thing blew the pressure plug. Blew it all over the ceiling. BIG mess!
Maybe you should try the crock pot method. I don't think the pressure cooker will work. Apple butter needs to thicken by reducing the liquid slowly. If you decide to try it, let me know how it turns out.
