3TbspJaegermeisterCan add loads more if you want, and you can also substitute for any spiced alcohol you have on hand.
Instructions
Bring the grapefruit juice and sugar to a boil in a saucepan and stir until the sugar is dissolved.
Remove from the heat, add the bitters and Jaeger and set aside to cool. Add to a shallow container and put in the freezer, stirring with a fork every half an hour or hour until frozen - you want a rough, flaky texture. Serve in chilled glasses!
