4 1/2 pounds very ripe peaches (about 20 medium), washed, blanched, peeled/ pitted, and cut into slices
4 cups of sugar + 1 heaping teaspoon cinnamon
puree peach slices in a food processor till they are pulpy (not liquid). combine peach pulp, sugar, and cinnamon in a large pot. cook until thickened, stirring frequently (approx. 30 minutes- will vary).
ladle hot peach butter into hot jars (follow proper canning procedures), remove air bubbles, adjust lids. process for 10 minutes (higher elevation 15) in a boiling water canner. yields about 5 pints.
warning/good thing, depending on your view of it: eating massive amounts of peach butter on costco's honey walnut wheat bread will result in a cleansing of the bowels.
