If you'd like to store your apple butter long-term, it's super easy to can it! This water bath canning set
has everything you need. While the apple butter is still hot, ladle it into hot sterilized jars, leaving 1/4 inch headspace, and process the jars in a water bath for 15 minutes. The apple butter will store in a dark, cool place for up to a year.
Alternatively, freeze or store in the fridge in air-tight jars for at least a month.
Makes about 5 pints.
