The BA Test Kitchen likes Grade B maple syrup for its deep and rounded flavor.
Ingredients
1 10-ounce bag frozen blackberries, thawed
3 tablespoons fresh lemon juice
2 tablespoons sugar
1 cup pure maple syrup
Directions
Bring blackberries, lemon juice, and sugar to a boil in a medium saucepan. Reduce heat and simmer, stirring occasionally, until berries soften and juices thicken slightly, 10–15 minutes. Remove from heat; stir in maple syrup. Let cool slightly before serving.
DO AHEAD: Syrup can be made 1 day ahead. Let cool; cover and chill.
