1 cup fresh blackberries, plus extra for topping if desired
Zest and juice of 1 small lime
4 tablespoons powdered sugar, divided
1 cup cold heavy cream
1 teaspoon vanilla
Instructions
Place the metal mixing bowl of your electric mixer and the whisk attachment in the freezer to get ice cold. Then, in a sieve placed over a medium bowl, press the blackberries through the mesh with the back of a spoon to get all of the juice and pulp into the bowl.
Take the bowl and whisk out of the freezer and attach to mixer. Pour in the cold cream, remaining 1 tablespoon of powdered sugar, and the vanilla. Mix on high speed until soft peaks form, a few minutes.
Gently fold the blackberry-lime mixture into the whipped cream. Gently spoon into 2-4 serving dishes or glasses. Top with extra blackberries and extra lime zest if desired. Serve immediately.
