Canning time 10 minutes
Total Time-ish 1 hour 10 minutes
Serving Suggestion 4 pints


  • 8 Cups Blackberries, washed
  • 2 Cups Raw sugar
  • 1 Tbsp. Lemon juice, pasteurized (not fresh)
  • 1-3 Under-ripe or tart apples, grated *If small, use three; if large, use one


  1. Place a metal spoon in your freezer.

  2. Wash blackberries and apples.  Core apples, but do NOT peel.

  3. Combine apples, blackberries and lemon juice in a large, heavy bottomed pot.  Cook until soft.

  4. Add sugar and stir to dissolve.  Cook on medium-high heat until boiling, stirring constantly.  Cook until mixture is reduced by at least a third, possibly a half.  Don't forget to stir to prevent scorching!

  5. After mixture has reduced, remove spoon from freezer and scoop a bit of jam onto it.  Do "the spoon test" as per the instruction in the "Notes" section.  

  6. Bottle quickly into pint jars, remove air bubbles with a knife down the inside of the jar, wipe rims and place seals on top.  Process in a water bath canner for ten minutes, adjusting for your altitude.

Recipe Notes

To conduct "the spoon test" to test for jam set, do the following.

  • Place some jam on your frozen spoon.
  • Watch to see if the jam sets up on the spoon after about a minute. 
  • Dump the fruit part back into the jam in the pot and run your finger down the spoon in the syrupy stuff left behind. 
  • Does your finger leave a trail?  Is the syrup holding its position?  If so, your jam is ready to be bottled and canned. 
  • If not, you can add a 1/2 cup more sugar if you'd like and/or continue cooking and stirring until set has been achieved.
