4 c. peaches (peeled, pitted, chopped sm. pieces)
1/4 c. lemon juice
7 1/2 c. (3 1/4 lbs.) sugar
1 tbsp. cinnamon
1 1/2 bottles Certo fruit pectin

Place fruit, juice, sugar and cinnamon in large saucepan; mix well. Place over high heat and full rolling boil and boil hard for 1 minute, stirring constantly. Remove from heat and stir in Certo at once. (Skim off foam with metal spoon. Stir and skim for 5 minutes to cool slightly and prevent floating fruit.) Ladle into glass jars. Cover with lid or 1/8 inch hot paraffin. Jars and lids should have been put in boiling water for 5 minutes before using.
