  • 5-6 lbs assortment of blackberries and raspberries
  • 4 cups sugar
  • 1/4 cup fresh lemon juice
  • 6-8 8-oz jars with unused lids


  1. Rinse berries gently in cold water.  Strain.
  2. Place berries in a large bowl and gently stir in sugar. Place in refrigerator overnight to allow berries to   macerate and sugar to dissolve.
  3. Press the mixture through a food mill or through a mesh strainer to remove seeds.
  4. Pour the mixture into a large heavy pot and simmer until mixture begins to thicken. Test the jam by putting a tablespoon of the mixture on a plate then placing in the freezer for a few minutes. Remove from freezer, if the jam holds a mound, it is done.
  5. Meanwhile place jars and lids in a large pot of hot water. Keep hot while jam cooks.
  6. Ladle jam into hot jars.
  7. Wipe the rims of the jars with a wet damp cloth.
  8. Screw on lid and bands
  9. Place in a pot of boiling water. Make sure the jars are covered with 2-inches of water.  Boil for 10 minutes. Remove from water and place on layers of clean towels until cool and jars have sealed.
