Making your own is the route I would go. There are a million ways to do it, but as I do not use sugar in mine, I find a quicky-method easiest:
Peel and chop an apple, add a touch of water, cover and cook on stove, stirring and mashing on occasion. Add sugar and cinnamon/nutmeg if you wish, cool then chow down. This is the same method I use when canning, only I use more than 1 apple and I put it in jars...
