Ingredients

  • 2 cups crushed strawberries (about 1 qt. fully ripe strawberries, stems removed)
  • 4 cups granulated sugar
  • 3/4 cup water
  • 1 box Sure Jell Fruit Pectin (*see note)
  • Containers to put the jam in - I like to use half-pint mason jars

Instructions

  • Rinse and dry the containers you'd like to put the jam in (enough for 5 cups). I always use glass mason jars but plastic containers work great also. This recipe fills 5-6 half pint jars.
  • In a food processor add strawberries and pulse just a few times, until strawberries are well diced, but not totally mashed. 
  • Measure exactly 2 cups of strawberries into a large bowl. (It's really important to measure the berries and sugar exactly, or the jam will not set properly.) 
  • Add the sugar, one cup at a time, stirring really well after each addition. Let stand for 10 min., stirring occasionally.
  • Meanwhile, add water and pectin package to a small saucepan. 
  • Bring to a boil over high heat, stirring constantly. 
  • Once boiling, stir for 1 min. Remove from heat and add it to the strawberry mixture. 
  • Stir mixture really well, for several minutes, until sugar is well dissolved.
  • Fill containers with jam and leave 1/2'' of head-space at the top. 
  • Cover with lids and allow to stand at room temperature for 24 hours.
  • After 24 hours you can store jam in the refrigerator for up to 4 weeks or freeze it for up to 1 year!

Notes

*Try the "No Sugar Needed SURE-JELL fruit pectin if you'd like to make this strawberry jam recipe with less sugar! *If for some reason your jam is runny and doesn't set up properly, you can pour it all back into a mixing bowl, boil another package of pectin, and add it to the jam.
