Use dry measuring cup to measure exact amount of prepared fruit, or use liquid measuring cup to measure exact amount of prepared juice, into large saucepan. Stir in lemon juice and water if listed in recipe.
Measure exact amount of sugar into separate bowl. (DO NOT REDUCE THE SUGAR IN THE RECIPE SINCE THAT WILL RESULT IN SET FAILURES.)
Stir 1 pkg. SURE-JELL Premium Fruit Pectin into prepared fruit or juice in saucepan. Add ½ tsp. butter or margarine to reduce foaming, if desired.
Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly.
Add sugar to fruit mixture in saucepan. Return to full rolling boil; boil exactly 1 min., stirring constantly. Remove from heat. Skim off an fam with metal spoon.
Ladle immediately into prepared jars, filling each within ¼ inch of top. Wipe jar rims and threads. Cover with two-piece lids. Place jars on elevated rack in canner. Lower rack into canner. (Water must cover jars by 1-2 inches. Add boiling water, if needed.) Cover; bring water to gentle boil. Process jellies 5 mi. or process jams 10 min., adjusting processing time if necessary as directed in Altitude Chart. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing centers of lids with finger. If lid springs back, lid is not sealed and refrigeration is necessary. Let prepared jars stand at room temperature 24 hours (of for length of time indicated on recipe). Store unopened jams and jellies in cool, dry, dark place up to 1 year. Refrigerate opened jams and jellies up to 3 weeks.
