Blackberry Syrup (Homemade Canning Recipe)

Instructions:

1. Prepare a boiling water bath canner and keep 6 half-pint jars hot until ready to fill.
2. Wash and sort the blackberries, removing any stems or damaged berries.
3. Combine the blackberries and water in a large saucepan. Bring to a gentle boil, then simmer for about 10 minutes, stirring occasionally.
4. Pour the cooked berries through a damp jelly bag or fine-mesh strainer. Allow the juice to drip naturally without pressing to produce the clearest syrup.
5. Measure 5 cups of blackberry juice into a clean saucepan.
6. Stir in the granulated sugar and bottled lemon juice.
7. Bring the mixture to a full rolling boil, stirring until the sugar has completely dissolved. Boil for 1 minute.
8. Remove the syrup from the heat and skim off any foam, if desired.
9. Ladle the hot syrup into the prepared hot jars, leaving 1/4-inch headspace.
10. Remove any air bubbles if necessary and wipe the jar rims clean.
11. Apply the lids and bands until fingertip tight.
12. Process the jars in a boiling water bath:
    • Half-pint jars: 10 minutes
    • Pint jars: 10 minutes
    • Adjust the processing time for your altitude if necessary.
13. Carefully remove the jars and allow them to cool undisturbed for 12–24 hours. Check that each lid has sealed before storing.

Variations

• Add a cinnamon stick while heating the juice for a warm, spiced flavor.
• Stir in a teaspoon of vanilla extract after removing the syrup from the heat for extra richness.
• Add a few sprigs of fresh thyme or rosemary during cooking, then remove before canning for a subtle herbal note.
• Replace a portion of the blackberries with raspberries for a mixed berry syrup.
• Add the finely grated zest of one lemon for a bright citrus twist.

Tips

• Use fully ripe blackberries for the sweetest flavor and deepest color.
• Let the juice drip naturally through the jelly bag or strainer without pressing to keep the syrup beautifully clear.
• Stir until the sugar is completely dissolved before bringing the mixture to a full boil.
• Always use bottled lemon juice to provide consistent acidity for safe home canning.
• Enjoy this homemade blackberry syrup over pancakes, waffles, French toast, cheesecake, ice cream, yogurt, or oatmeal. It’s also delicious stirred into lemonade, iced tea, sparkling water, cocktails, mocktails, or brushed over cakes for an extra burst of blackberry flavor.
