Ingredients You Need to Make Blackberry Syrup

Blackberry Syrup Ingredients on a white marble board.
  • Blackberries: Look for plump, deeply colored fresh blackberries that are free from mold and soft spots. If using frozen berries, thaw them first.
  • Agave Nectar: Choose between light and dark agave nectar. Light agave has a mild, almost neutral flavor, while dark agave offers rich, caramel-like notes.
  • Water: Filtered water is ideal. If you’re using tap water, make sure it’s free from any odors, as they could affect the syrup’s taste.

Recipe Options

  • Instead of agave nectar, you can use honey for a more floral undertone or maple syrup for a hint of smokiness.
  • If blackberries aren’t your favorite, raspberries or blueberries make excellent substitutions. Or use a mix of berries!
  • For some citrus zing, add a teaspoon of lemon or lime zest to the blender.
  • Mix in a splash of vanilla extract for added complexity.
  • Stir in a pinch of cinnamon or nutmeg for a warm, spiced flavor.

Recipe Tips

  • Use a fine mesh strainer to be sure that the seeds and solids are removed, giving you a smoother syrup.
  • If you find the syrup too thin, reduce the amount of water in your next batch or add more blackberries for a thicker consistency.
  • Remember to shake or stir the syrup before use, especially if it has been sitting in the refrigerator, to redistribute any settled ingredients.

How to Store

Store the syrup refrigerated in a clean glass jar (ideally sterilized) with a tight seal. Enjoy it within 1 week.

    Blackberries are my favorite berry, so of course I would be all over this blackberry syrup! A drizzle of this over a good vanilla ice cream would be an awesome dessert.
