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.
- Rinse fresh blackberries (if using) and drain thoroughly. If using frozen, no need to rinse – just let them thaw slightly.
- 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.
- Combine the blackberries, sugar, and the lavender-lemon mixture in a medium-sized saucepan. Stir gently to combine.
- 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!
- 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!
- (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!
- 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.
