American Blueberry Gin Smash

To make the raspberry mint syrup, use a 1:1 ratio of sugar to water, heated on the stovetop until the sugar dissolves. Add at least a half cup of fresh raspberries (more if making a large batch) and a few leaves of fresh mint (or mint tea in a pinch), bring to a boil, and then take it off the heat. Cover and set aside to infuse until it tastes of raspberry. Strain and store in the fridge until ready to use. To make the drink, muddle blueberries in your shaker tin, then add the other ingredients...
