Notes
Store fresh citrus at room temperature for best juicing results. The juice should be squeezed right before mixing the drink.This recipe makes one serving. Double or triple the amounts to serve more people.Keep simple syrup in the fridge for up to 2 weeks in an airtight container.For a non-alcoholic version, replace vodka with extra club soda and a splash of tonic water.
