Recipe by Ballyvolane House 
This is the cocktail that Ballyvolane House serve in spring/summer as rhubarb is in season and it is grown in their walled-garden.
A couple of these before dinner promises lively conversation throughout dinner. They are delicious and very easy to make.

Rhubarb Syrup:

Boil the sugar and water to make sugar syrup. Once the sugar has dissolved, add the chopped rhubarb (2 inches long) and grated ginger and poach gently until the rhubarb is soft.Allow to cool for one hour and strain the rhubarb through a sieve. Decant the rhubarb syrup into a bottle and store in the fridge. It will keep for a couple of weeks in the fridge and it freezes really well too.

2 Rhubarb Martinis:

When using a cocktail shaker, always avoid trying to make too much quantity in one go as the cocktail doesn’t mix well when full. Mixing two Martinis in one shaker is best. Put all the ingredients together into a cocktail shaker and shake vigorously for 30 seconds. Hold the shaker in two hands and shake it over your shoulder. Chill the Martini glasses by putting them in the freezer or leave a few lumps of ice in them for a few minutes. Pour the Rhubarb Martini through a cocktail strainer into the glasses. Always taste before pouring and add more syrup if too sour or more lime juice if too sweet. 

Enjoy!
