Fattening? Nothing like as much as jam??
Keeping? Use?
"Apple butter is like a thicker and spicier version of applesauce. It is great on toast, crackers, cornbread, pancakes etc., or over ice cream. Make it as plain or as spiced-up as you like. This recipe is a good starting place. If you don't want to bother with canning, just freeze whatever apple butter you won't be using within a week."
Or with cheese & meats?
PS Cook in Cider also - or no liquid if long & slow.
