Here is an experiment I came up with during my quest to create the perfect martini. It’s very thick and it WILL stain if you spill it, so wear a bib or just be very careful!
1/2 cup frozen berries (cherries, blueberries, raspberries, blackberries)
1/8 cup water
2 tsp sugar
2 oz vodka
Purée the berries, sugar, lime, and water in a blender. Mix this with the vodka and ice cubes in a cocktail shaker.
