Mmmm... Fresh blueberry jam on your toast in the morning!
1 1/2 qt. blueberries (fresh or frozen, thawed/not drained)
2 tbsp. lemon juice
1 box Sure-Jel or Can-Jel
4 c. sugar
Remove stems and crush fully ripe blueberries completely, one layer at a time.(Or blend them coarsley in a food processor.) Measure 4 cups of crushed fruit. Add more berries if necessary. Place berries in a very large kettle and stir in the lemon juice and the Sure-Jel or Can-Jel. Place over high heat and stir until the mixture comes to a hard boil. Immediately add the sugar and bring to a full rolling boil; boil hard 1 minute, stirring constantly.
Remove from heat; skim off foam with metal spoon; stir and skim 5 minutes to cool slightly and prevent floating fruit. Ladle into sterilized glass jars, leaving 1/2" space at top. Seal with lids.
This recipe makes about 7 cups or 3 1/2 pints of jam.
