The heart-shaped box is perhaps one of the most criminally-underappreciated cocktails in the death & co: modern classic cocktails book. Created by brad farran, its an explosion of inventive flavors with a perfect balance between sweet, spiced, and tart elements. That little bit of balsamic vinegar is a master stroke, uniting the strawberry and lemon and cinnamon with its rich, raisin-y flavor. The whole thing smells incredible, like a newly-discovered fruit on some distant planet.
