Blueberry Syrup

Ingredients

  • 2 cups (10 oz) blueberries
  • 1 cup + 2 Tbsp blueberry juice, grape juice or apple juice, divided
  • 1/3 cup granulated sugar*
  • 4 tsp cornstarch
  • 1 Tbsp lemon juice

Instructions

  • Add blueberries, 1 cup juice and sugar to a small saucepan, stir. Bring to a simmer over medium-high heat.
  • Reduce heat to low and let simmer 6 - 10 minutes, stirring occasionally, until many of the blueberries have burst.
  • In a small bowl whisk together remaining 2 Tbsp juice with the cornstarch then pour into pan. Let simmer 1 minute longer to thicken while stirring constantly.
  • Remove from heat. Stir in lemon juice.
  • If desired press and strain through a mesh sieve to remove skins, blitz in a blender (be sure to remove lids center insert and cover with a towel to blend since it’s a hot liquid), or serve as is.

Notes

  • *Sugar can be increased or decreased to taste. Sometimes blueberries are tart and need a little more while other blueberries can be super sweet.
  • You can also use 2.5 Tbsp sugar and 2.5 Tbsp honey instead.
  • Fresh or frozen blueberries can be used here. Fresh are best but when not in season frozen work well too.
