Rhubarb Simple Syrup

Rhubarb Simple Syrup

Rhubarb simple syrup is a really easy and delicious syrup to use in drinks, cocktails, lemonade or even hot beverages. The rhubarb adds a beautiful pink color to the simple syrup and an almost apple note to the taste.

If you are a fan of rhubarb then you definitely need to try this simple syrup. My favorite way to use this syrup is in lemonade and Aperol cocktails and my spicy Miami vice cocktail.

Making this simple syrup requires very little time to make but you will want to plan for at least four hours of cooling time to make sure it is chilled before using. You can use fresh rhubarb or frozen rhubarb, whatever you have available. I wasn’t able to get fresh rhubarb so I used frozen.
