Rhubarb vodka

Method

1. Chop the rhubarb into thin slices and put in the jar. Add the sugar, the orange zest and vodka. Seal and store in a dark cupboard for 6-8 weeks (the longer the better), turning or gently shaking every now and then to dissolve the sugar and redistribute the rhubarb. Strain the vodka through a square of muslin, then transfer to a screw-top glass bottle. Serve chilled in shot glasses.
