Cinnamon and sugar can be added to flavor the butter however, persimmons have such a sweet and delicate flavor, I usually don't add them.
CANNING SAFTEY: Persimmon has a pH value right on the cusp of being unsafe for water bath canning, I suggest combining persimmons with another more acidic fruit and always use bottled lemon juice. I follow tested water bath canning methods for this recipe but store the sealed, small batches in the refrigerator for up to one month.
