Ingredients

  • 2 cups frozen Marionberries from Oregon
  • 1 loose cup Sugar
  • 1 cup water
  • 1 cinnamon stick broken into two
  • 6 cloves whole
  • Pinch of salt
  • 1/2 teaspoon gelatin in 1 tablespoon water

Instructions

  1. Use a cheesecloth and wrap the whole spices in it, tying it well. Alternatively, you can use a whole vanilla bean, or orange and lemon peels for flavoring.

  2. In a large pot add in the berries, sugar and water, mix those well.

  3. Use a potato masher to slightly mash the berries or leave them whole if you prefer a chunkier blackberry jam.
  4. Place the pot over medium high heat and as soon as the sugar starts to dissolve, add in the spices in cheesecloth.

  5. Drop the heat to medium low and stir the jam frequently for about 20 minutes until it starts to thicken. The majority of the water would have been evaporated and the flavour of the berries would have intensified.

Recipe Notes

Blackberry Jam Tips

  1. For the best tasting blackberry jam recipe, always start with quality berries like Oregon berries.
  2. Try Marionberries from Oregon instead of blackberries for a unique tasting jam.
  3. Have full control over the sweetness of the jam by adding more or less of the sugar.
  4. As a general rule, it’s best to use a ratio of 1:2 sugar : fruit.
  5. Similar ratio used with the water here is 1:2 water : fruit.
  6. Flavoring the jam is key to a delicious tasting jam recipe! Vanilla beans, citrus zests, ginger, and whole spices are great options.
  7. When using those flavoring items to the jam, make sure to use whole large items which you can boil with the fruit and remove later once the jam is ready.
  8. Avoid using powders or fine zests as this will cause a bitter aftertaste to your jam eventually.
  9. For smaller spices (like I have here), it’s best to wrap them in a thin cheese cloth while cooking with the berries so that you may easily remove them.
  10. Thickening of the jam is completely up to your taste. Feel free to skip or experiment based on the recipe below.
  11. Don’t be overwhelmed by making lots of jam and the canning process at first, rather start with this small batch blackberry jam recipe.
  12. Freezing extra jam in ice cube trays is my my favorite trick to storing extra jam!
    ENJOY the process :)
