Ingredients
 
 

  • 2 Tablespoons cornstarch
  • 2 Tablespoons water
  • 450 g blueberries fresh or frozen
  • 70 g granulated sugar can be decreased if blueberries are very sweet or increased if tart
  • 1 Tablespoon lemon juice
  • 1 teaspoon lemon zest optional
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt

Instructions
 

  • In a small bowl combine 2 tablespoons of cold water with the cornstarch. Mix it into a slurry. Set aside. 2 Tablespoons cornstarch , 2 Tablespoons water
  • In a medium saucepan add the blueberries, sugar, lemon juice, zest, vanilla, and salt. 450 g blueberries, 70 g granulated sugar, 1 Tablespoon lemon juice, 1 teaspoon lemon zest, 1 teaspoon vanilla extract, 1/4 teaspoon salt
  • Place the saucepan over medium-low heat and stir gently as the mixture begins to warm up and the blueberries release their juices
  • Once the mixture has come to a simmer, pour in the slurry and stir continuously as it thickens and becomes jelly-like and loses its cloudy appearance. Let it boil for around 1 minute, stirring continuously, before taking it off the heat. The cornstarch must be cooked through properly, or the filling can lose its thickness.
  • Tip into a bowl. As the mixture is cooling, cover it with plastic wrap, gently pressing it on the mixture. This stops a skin from forming.
  • Once cooled to room temperature, store in the fridge in an airtight container until needed.
