This dark and sweet blackberry summer cocktail is a must have for gin lovers. The gin's grassy and earthy bitterness mixes wonderfully with the bittersweet blackberry simple syrup. Ginger and blackberry are a flavor that always work well together, and the addition of our Ginger Liqueur is a wonderful asset to this refreshing drink. For a little foam, add an egg white and then some fresh blackberries and lemon zest for a classy touch. This drink looks as good as it tastes.
