Let's Make It
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 well before filling.
Crush youngberries thoroughly, one layer at a time. Press half the pulp through sieve to remove seeds, if desired. Measure exactly 6 cups prepared fruit into 6- or 8-qt. saucepot. Add lemon juice; mix well.
Stir pectin into prepared fruit in saucepot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in sugar. Return to full rolling boil; cook exactly 4 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
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 10 min. Remove jars and place upright on 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.) Let prepared jars stand at room temperature 24 hours. Store unopened jams and jellies in cool, dry, dark place up to 1 year. Refrigerate opened jams and jellies up to 3 weeks.
How to Measure Precisely
To get exact level cup measures of sugar, spoon sugar into dry measuring cup, then level by scraping excess sugar from top of cup with a straight-edged knife.
How to Crush Berries
Place washed and picked-over berries in a shallow bowl, then crush with a potato masher or pastry blender until desired consistency.
