Pick berries, wash well and drain, grind through old-fashioned food chopper and put in large container. Pour boiling water to cover berries and let stand overnight.
Next day, strain well through cheesecloth or old dish towel and measure juice. One batch of jelly takes 3 1/2 cups juice, 4 1/2 cup sugar (measured in bowl), 1 box Sure-Jell. Add Sure-Jell to juice in large kettle, bring to a boil, add sugar all at once and bring to boil again; boil at least 1 minute or until it "sheets" off the spoon or clings between tines of a fork dipped in jelly.
Sometimes this takes longer than 1 minute. Take from stove, let set for a few seconds and skim off foam with tablespoon; discard foam or eat as a "taster." Pour into clean jars and seal with a lid or paraffin melted and poured over when jelly is cooled.
