  • Fast: Ready in under 30 minutes!
  • Easy: Simple steps, even for beginners.
  • Giftable: Perfect for friends, family, and holiday baskets.
  • Crowd-pleasing: The unique flavor combination is a guaranteed hit.

Ingredients

  • 4 cups fresh or frozen blackberries: Fresh are best for the most vibrant flavor, but frozen work perfectly in a pinch!
  • 2 cups granulated sugar: This helps set the jam and balances the tartness of the berries.
  • 1 tablespoon dried culinary lavender (or 1 teaspoon fresh, finely chopped): This adds a beautiful floral aroma and a subtle lavender taste. Make sure it’s culinary-grade lavender.
  • 2 tablespoons lemon juice: Adds brightness and helps with setting.
  • 1 teaspoon lemon zest (optional): Enhances the citrus notes – I love adding this for an extra zing!

How to Make It

Let’s get jammin’! This recipe is so straightforward, you’ll be amazed.

  1. Rinse fresh blackberries (if using) and drain thoroughly. If using frozen, no need to rinse – just let them thaw slightly.
  2. In a small bowl, steep the dried lavender (or chopped fresh lavender) in the lemon juice for 5-10 minutes. This infuses the lemon juice with a lovely lavender fragrance.
  3. Combine the blackberries, sugar, and the lavender-lemon mixture in a medium-sized saucepan. Stir gently to combine.
  4. Bring the mixture to a simmer over medium heat, stirring occasionally. This will take about 20-25 minutes. As it simmers, some of the berries will naturally break down, but I like to gently mash a few with a potato masher for a smoother consistency. It’s totally up to you!
  5. To check for setting point, place a small spoonful of the jam onto a chilled plate. Let it cool for a minute. If it wrinkles when you push it with your finger, it’s ready!
  6. (Optional) For a smoother jam, strain the mixture through a fine-mesh sieve to remove seeds and lavender bits. I sometimes do this, sometimes I don’t – it really depends on my mood!
  7. Carefully transfer the hot jam to sterilized jars, leaving about ¼-inch of headspace at the top. Wipe the rims clean, seal tightly, and let cool completely. You can either refrigerate your jam or process it in a boiling water bath for 10 minutes for longer shelf life. (Always follow safe canning practices if water-bath canning).

Substitutions & Additions

  • Other berries: Raspberries, blueberries, or a mix would be delicious!
  • Spices: A pinch of cardamom or cinnamon would add warmth.
  • Citrus variations: Try orange zest and juice instead of lemon.

Tips for Success

  • Use ripe berries for the best flavor.
  • Don’t overcook the jam, or it might become too thick.
  • Sterilize your jars and lids properly to prevent spoilage. I usually wash them in hot, soapy water, then rinse and boil them for a few minutes.
  • Make this jam ahead of time – it’s even better after a few weeks!

How to Store It

Once cooled, store your Blackberry Lavender Jam in the refrigerator for up to 3 weeks. If you processed it in a boiling water bath, you can store it in a cool, dark pantry for up to a year.

FAQs

  • Can I use frozen blackberries? Absolutely! Just let them thaw slightly before using.
  • What if my jam is too thin? Simmer it for a few more minutes, or add a tablespoon or two of pectin.
  • Can I make this jam without lavender? Yes, but it won’t be quite as unique! You could add a different herb or spice instead.
  • How long does it take to make this jam? About 30 minutes, plus cooling time.
