3 jars of Rhubarb Syrup

Here's a refreshing rhubarb simple syrup for stirring into all your spring-inspired cocktails (or mocktails). It's a rosy syrup that requires just three ingredients and adds a unique flavor, dimension, and a beautiful red/pink hue.

If you're wondering what else to do with rhubarb syrup, it also makes a great substitute for maple syrup. Serve it over sweet breakfasts like pancakes, waffles, oatmeal, or even over ice cream (our favorite).

Rhubarb's growing season is short, so use the stalks to make a big batch of this syrup and keep its taste alive. Leftovers keep well in the fridge for up to a month!

Here's what you'll need

This syrup takes only three ingredients. Here's what you'll need:

  • Rhubarb – fresh or frozen both work in this recipe!
  • Water
  • Sugar

Tip: Look for stalks that are crisp, bright pink, and thin. Thinner and darker the stalks are the sweetest. Lighter stalks will be more tart, so you may want to adjust the sweetness of this recipe accordingly.

Rhubarb Syrup: FAQS

What kind of sugar should I use?

We use granulated (white) sugar. You could use brown sugar but it will make a darker syrup and have more of a caramel taste. Honey also works well for a refined sugar-free version!

How long does it last?

Rhubarb syrup will keep in the fridge in an air-tight jar or bottle for up to two weeks.
