  • 12 ounces fresh blackberries
  • 1 ½ cups granulated sugar
  • ¼ cup fresh tarragon leaves chopped
  • 3 teaspoons fresh lemon juice approximately ½ lemon
  • 1 pinch kosher salt


  • In a small pot, combine blackberries and sugar and mash with a fork or pastry cutter until the sugar is absorbed by the berries and no large lumps remain.
  • Add chopped tarragon, lemon juice, and salt and stir to combine.
  • Heat the pot on the stovetop over medium high heat and bring to a boil. Lower the heat to medium low and allow the mixture to simmer for 20 minutes, stirring occasionally, until reduced and slightly thickened.
  • Cool the jam off of the heat for 15 minutes and then pour into half pint mason jars or an airtight container to completely cool in the refrigerator.


  • Recipe yields enough jam to approximately fill two half pint mason jars.
  • Since the jam is not canned, it must be stored in the refrigerator or freezer. Stored in an airtight container, it will last up to 3-4 weeks in the refrigerator and up to 10-12 months in the freezer.
  • Blackberry jam will foam up quite a bit when simmering, especially at the beginning. Stir occasionally and reduce the heat if needed to prevent it from boiling over.

Substitutions and Variations

  • To make this blackberry jam seedless, process your blackberries through a food mill first to remove the seeds and mash them smooth.
  • If fresh tarragon is not available, 2 teaspoons of dried tarragon may be used instead.
  • Fresh basil, rosemary or thyme may also be used as a substitute for the tarragon.

Serving Suggestions

This homemade blackberry tarragon jam would go wonderfully on top of cinnamon applesauce muffins, honey wheat bread or even on a charcuterie board. It can also be used as a filling inside of a layered cake or cannoli cupcakes!
