Ingredients

Liquid Ingredients

  • 1/4 cup water (60ml)
  • 2 tbsp lemon juice (30ml)
  • 1 tsp vanilla extract

Dry Ingredients

  • 1/3 cup white granulated sugar (70g) OR 3 tbsp maple syrup or honey (60g)
  • 2 tbsp cornstarch (15g)
  • pinch of salt
  • 1 tsp lemon zest

Fruit

  • 4 cups fresh or frozen blueberries, divided (600g)

Instructions

  1. Combine liquids and dry ingredients: In a medium saucepan, whisk together the water, lemon juice, lemon zest, sugar (or maple syrup/honey), cornstarch, and a pinch of salt until smooth and no lumps remain.
  2. Heat the mixture: Place the saucepan over medium heat and stir constantly as the mixture begins to thicken and bubble, about 3-5 minutes. This ensures the cornstarch activates and the filling achieves a glossy, thick consistency.
  3. Add the blueberries: Stir in 3 cups of the blueberries and continue cooking for another 2-3 minutes until the berries soften and release their juice into the thickened sauce.
  4. Add remaining blueberries and vanilla: Stir in the remaining 1 cup of blueberries and the vanilla extract, allowing the sauce to heat through without breaking down the last berries completely to keep some texture.
  5. Cool and use: Remove the sauce from heat and let it cool slightly before using as a pie filling or topping. The sauce will further thicken as it cools.

Notes

  • You can substitute the sugar with maple syrup or honey for a natural sweetness alternative.
  • Adjust the sweetness according to your taste; add more sugar or syrup if desired.
  • For a smoother sauce, you can mash some of the blueberries during cooking.
  • Use fresh or frozen blueberries directly without thawing.
  • Store leftover sauce in an airtight container in the refrigerator for up to one week.
