Blackberry liqueur, also known as creme de mure, is a summer must! It has the brightness of berries and the richness of a sophisticated liqueur all rolled into one.
Note: If using frozen berries, defrost them first. Blackberry juice can stain clothes and counter tops, so be careful and clean up spills right away. The touch of lime adds another dimension to the liqueur and brings out the fresh tartness of the berries, but you can leave it out or substitute lemon, if desired. To make simple syrup, combine 1 cup water with 1 cup sugar in a small saucepan and heat over medium heat, stirring constantly, until sugar is dissolved. Cool before using. Simple syrup will keep in a sealed container in the refrigerator for up to 5 days.
