Ingredients

Scale
  • 4 cups fresh or frozen mulberries
  • 3/4 to 1 cup granulated sugar
  • 3 tablespoons cornstarch
  • 2 tablespoons lemon juice
  • 1 teaspoon vanilla extract
  • 1/4 cup water

Instructions

  1. Rinse fresh mulberries gently under cool water and remove any stems. If using frozen mulberries, measure them directly from the freezer.
  2. In a medium saucepan over medium heat, combine mulberries, sugar, lemon juice, and water. Stir occasionally as the berries release their juices.
  3. In a small bowl, mix cornstarch with 1–2 tablespoons of water to create a smooth slurry.
  4. Once the berry mixture begins to bubble, slowly pour in the cornstarch slurry while stirring constantly.
  5. Continue cooking for 3–5 minutes until the filling thickens and becomes glossy, coating the back of a spoon.
  6. Remove from heat and stir in the vanilla extract.
  7. Allow the mulberry pie filling to cool completely before using in pies or storing.

Notes

  • If using frozen mulberries, you may need an extra 1/2 tablespoon of cornstarch due to added moisture.
  • The filling will thicken more as it cools, so avoid overcooking.
  • Store in an airtight container in the refrigerator for up to 5 days.
  • Freeze for up to 3 months in freezer-safe containers.
  • For a smoother texture, lightly mash some of the berries while cooking.
