Pour water and sugar into small heavy saucepan, add washed blueberries and fresh mint if desired.
Over medium heat stir until sugar dissolves, bring mixture to simmer, without stirring for about 3 minutes. BUT DO NOT BOIL.
Cool completely, in pan, then pour cooled syrup through strainer into a bowl, if desired smash blueberries with back of spoon for a slightly thicker syrup. Pour into clean 16 oz mason jar, storing in fridge. Lasts about 1 month in fridge.
BLUEBERRY LIMEADE (or Lemonade)
This step is optional, but adds a lovely sweet-tart surprise and makes the blueberry lemonade or limeade a bit fancier.
Place the sugar on a medium sized plate, using your fingers, rub the lime zest into the sugar, flavoring the sugar. Rub a wedge of lime (or lemon) around the edge of the glass, then turn the glass upside down and rotate to coat the rim of the glass in the lime sugar. Measure (or eyeball) the blueberry simply syrup and pour over ice in glass.
Add desired amount of lemonade or limeade for your blueberry drink! Stir to combine.
Be sure to add plenty of ice, then add 1/2 - 1 cup blueberry simple syrup and stir in 52-64 oz of your favorite lemonade or limeade.
Tuck plenty of fresh mint, slices of lemon or lime and a few fresh or frozen blueberries for a gorgeous summer beverage.
