Rinse the cherries and pick out any bruised or damaged fruit.
Use a pair of kitchen sheers to trim the stems to about 1/2" long.
Pack the cherries into a jar, filling it tightly and to the top.
Use a funnel to fill the jar about 1/3 of the way with sugar.
Fill the jar to the top with vodka and seal the lid on tightly.
Shake and roll the jar in your hands until the sugar has dissolved.
Place the jar in a cool dark spot for six months, rolling or shaking the jar every month.
