🍹 Ingredients

Not much to this recipe at all. Here is what you will need:

  • Chopped rhubarb
  • Sugar
  • Water

See the recipe card for quantities.

🍲 Instructions

Take this vegetable (because rhubarb is a vegetable) and infuse it into sugar water. It is as simple as that. 

A few things to consider when making this simple syrup are how thick you want the syrup and how much of a rhubarb flavor you want. Simmering this longer than the recipe recommends will give you a thicker syrup. 

The syrup might not show its full thickness until it has cooled down. Right off of the stovetop, the liquid will be a bit more fluid and as it cools down, the true viscosity will be known. 

Of course, you can simmer it a second time to make it thicker AND give it a more concentrated rhubarb flavor. You could add more rhubarb to the mix, but our recipe provides an outstanding balance of flavor, sweetness, and viscosity for a great cocktail mixer.

🤷 Substitutions and variations

You can change this recipe up in a few ways:

  • Herbs – Consider adding some herbs to the boil. A pinch of rosemary or thyme would be great
  • Strawberry – Strawberry is a natural companion to rhubarb, and adding some strawberry rhubarb syrup is very tasty! 
  • Sweetener – Try honey or maple syrup to make this an even more interesting syrup.

📦 Storage

After straining the rhubarb syrup, it should be put into a sealed container, stored in the fridge, and used within a month. It’s important to cool the syrup before sealing the container and storing it.

  1. I’ve never had rhubarb but that may change! I’m loving the vibrancy of the syrup! Plus the recipe is so easy too!

  2. Made this with my first batch of rhubarb this afternoon, and enjoyed it in an old fashioned this evening. It was delicious!

  3. It’s just as my mom used to make when I was young. It can be mixed with soft drinks like Sprite or Casera, or added to cocktails. Most of the time we just dilute it in some plain water and enjoy. I also freeze it with success.
