A sweet, buttery homemade blueberry syrup with bright lemon flavor and juicy fresh blueberries. Perfect for pancakes, waffles, French toast, desserts, and more.

Ingredients

  • 1 tablespoon (8g) cornstarch
  • 2 teaspoons cold water
  • 1 cup (200g) granulated sugar
  • ¾ cup filtered water
  • 1 cup fresh blueberries
  • 2 tablespoons butter (salted or unsalted is fine)
  • 1 teaspoon lemon juice (preferably fresh)
  • 1 teaspoon grated lemon zest (optional)
  • 1 pinch salt
  • ½ cup fresh blueberries (optional for mixing into syrup)

Instructions

  1. In a small bowl, stir together the cornstarch and 2 teaspoons cold water to make a slurry. Set aside.
  2. In a small saucepan, combine the sugar and ¾ cup water. Cook over medium-high heat, stirring constantly, until the mixture comes to a boil and the sugar is completely dissolved, about 4-5 minutes.
  3. Stir in 1 cup blueberries and the cornstarch slurry. Bring to a simmer, then reduce the heat to maintain a gentle simmer.
  4. Simmer for 10-15 minutes, until the syrup has reduced and slightly thickened. It should thickly coat the back of a spoon.
  5. Remove from the heat and stir in the butter, lemon juice, optional lemon zest, and salt.
  6. For a completely smooth syrup, strain the mixture. For a chunkier blueberry sauce, stir in the optional additional ½ cup fresh blueberries.
  7. Let the syrup cool for 10-15 minutes before serving.
  8. Serve over pancakes, waffles, French toast, desserts, or your favorite dish.

Notes

  • The cornstarch slurry helps create a thicker syrup consistency.
  • Strain the finished syrup for a smooth texture or add extra fresh blueberries for a chunkier sauce.
  • Fresh lemon zest is optional but adds extra citrus flavor.
  • The syrup will continue to thicken slightly as it cools.
