Manitoba is full of apples and apples are full of butter…or something like that.
Fill a slow cooker with tart apples (quartered, don’t peel or core). Cook on low for 18 hours. Strain to get rid of the seeds and skin, then add sugar, cinnamon, and cloves (all to taste). Cook for another 4 hours. If canning, process the filled jars for 10 minutes.
