Peach Hot Pepper Jelly
2 c. finely chopped peeled peaches (about 1 1/2 lbs.)
1 c. finely chopped red pepper (about 1 large red pepper)
1 c. finely chopped jalapeno peppers (about 10 peppers)
1 c. apple cider vinegar
1 pkg. Sure Jell Fruit Pectin
1/2 t. butter or margarine
5 c. sugar, measured into a separate bowl and set aside.
Place peaches and peppers in 8 qt. saucepan. Add vinegar. Stir in pectin. Add butter to reduce foaming. Bring to a full rolling boil on high heat, stirring constantly.
Stir in sugar. Return mixture to a full boil and boil for 1 minute, stirring constantly.
Skim off any foam with a spoon.
Immediately ladle into prepared jars, leaving 1/4 inch headspace. Wipe jar rims and cover with 2 piece lids. Place filled jars in a water bath canner on a rack. Cover with water 1 to 2 inches above the tops of the jars. Cover canner and bring to a gentle boil. Process for 10 minutes. (Check to see if you need more time for your altitude.)
Remove jars and place on a towel to cool. Check seals and label jars for storage.
