Place blueberries into a small saucepan with lemon juice, zest and sugar. Simmer over low heat until the sugar dissolves and the blueberries start to break open. Mash half of the blueberries with the back of a fork, leaving some full blueberries behind.

Pour into a small bowl and cool in the fridge for an hour.

Remove Lemon Ginger Whips from freezer.

With a mandolin, thinly slice 1 whole lemon. Place lemon slices on serving dishes. Unwrap whips and place on lemon slices. Spoon blueberry sauce over and serve.
