Ingredients
4-1/2 cups
prepared fruit (buy 2 fully ripe medium pineapples)
1/2 tsp
butter or margarine
5-1/2 cups
sugar, measured into separate bowl
Instructions
Step 1
Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain jars well before filling.
Step 2
Peel and core pineapples. Finely chop or grind fruit. Measure exactly 4-1/2 cups prepared pineapple into 6- or 8-qt. saucepot. Stir in pectin. Add butter to reduce foaming. Bring to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly.
Step 3
Add sugar. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
Step 4
Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 5 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)
