To all my friends picking blueberries here a recipe I bet you did not think of:
The Blueberry Rum Smash makes 1 cocktail
Fresh (or frozen) blueberries
1 tablespoon brown sugar
3/4 ounce fresh-squeezed lemon juice
2 ounces rum
Cover the bottom of an old-fashioned glass or mason jar with blueberries. (If you’re using a smaller glass, make a double layer.) Add the brown sugar and lemon juice and muddle (or smoosh with the back of a spoon) until the sugar is melted. The idea is to break the skins of the blueberries, but not to mash them into a pulp. Fill the glass with crushed ice and then add the rum. Top with ginger ale and stir.
