Ingredients

Scale

Jam Ingredients

  • 1 quart fresh or frozen blueberries (1½ pounds / 680 g)
  • 8 oz / 227 g honey
  • ½ lemon, zested and juiced
  • 1 Tablespoon fresh lavender buds (preferably organic)

Instructions

  1. Prepare the Lavender: Grind the fresh lavender buds gently in a mortar and pestle to release their fragrance and flavor. Set aside this lavender powder for later use. If you plan to can the jam for long-term storage, sterilize three half-pint canning jars, lids, and rings, and prepare a water bath canner.
  2. Cook the Berries: Place small glass or ceramic bowls into the freezer to chill – these will be used later to test the jam’s set. In a large, wide skillet, combine the blueberries, honey, lemon juice, and lemon zest. Heat the mixture over medium heat, allowing the blueberries to cook down. Use the back of a large spoon to mash the berries to your desired chunkiness; this step is optional based on your preferred jam texture.
  3. Bring the Jam to the Setting Point: As the mixture simmers, it will begin to foam. Regularly scrape off the foam to improve the jam’s appearance (the foam is edible and can be saved for use as a sweet topping). Continue cooking the jam until it reaches the setting point, approximately 105°C (220°F).
  4. Test the Setting Point: Remove one of the chilled bowls from the freezer and spoon a small amount of jam onto it. Return the bowl to the freezer for 2-3 minutes. Take it out and gently push the jam with your finger tip; if it wrinkles, the jam is set. If not, continue cooking and repeat the test, pausing cooking as needed to avoid overcooking.
  5. Process the Jam in a Water Bath: Once the jam is set, remove it from heat and add the ground lavender buds. Stir to incorporate evenly. Pour the hot jam into the sterilized half-pint jars, leaving appropriate headspace. Seal the jars with prepared lids and rings, then process them in a boiling water bath canner for 10 minutes for safe preservation. If you prefer not to can, allow jars to cool to room temperature and refrigerate for immediate use.

Notes

  • You can adjust the amount of lavender to taste, but avoid overuse as it may become overpowering.
  • Using a wide skillet helps to reduce cooking time by increasing surface area for evaporation.
  • The foam that forms during cooking can be saved and used as a delightful topping on desserts like ice cream.
  • If you don’t have a candy thermometer, the freezer test is a reliable way to check jam set.
  • Sterilize jars carefully and follow proper canning procedures to ensure shelf-stability.
