Equipment

  • Mixing bowl
  • Saucepan
  • whisk
  • Fine-mesh strainer
  • Jar or Bottle
  • Stovetop

Ingredients
  

Syrup Base

  • cup fresh blueberries
  • cup brewed coffee strong, reduced amount for thickness
  • cup granulated sugar
  • tbsp lemon juice
  • tsp cornstarch optional for extra thickness
  • pinch salt
  • tsp vanilla extract

Instructions
 

  • Lightly mash blueberries in a bowl to release juices while keeping some texture.
  • Add blueberries, coffee, sugar, and lemon juice to a saucepan. Stir well.
  • Bring to a gentle simmer over medium heat, stirring until sugar dissolves fully.
  • Cook for 10–12 minutes, allowing mixture to reduce and thicken noticeably.
  • If needed, stir in cornstarch slurry and cook briefly until syrup thickens further.
  • Check texture; syrup should heavily coat the back of a spoon.
  • Remove from heat, stir in vanilla and salt, then cool before storing.

Notes

Simmer longer for thicker texture or add cornstarch for extra body. Chill to firm consistency. Freeze in small portions for longer storage. Stir before use if separation occurs. Adjust sugar or lemon for balance. Store refrigerated up to one week in an airtight container.
