Our rhubarb syrup is a delicious, sweet-tangy delight that takes 15 minutes to make and only calls for three simple ingredients: rhubarb, sugar, and vanilla. With its stunning color and fresh flavor, it provides a unique way to incorporate rhubarb into cocktails, non-alcoholic drinks, desserts, and more. Making it is similar to whipping up any other simple syrup: You’ll combine equal amounts of sugar and water, plus the chopped rhubarb and vanilla bean, and simmer until the sugar is dissolved and the rhubarb is tender. After straining, it’s ready for drizzling on ice cream, folding into whipped cream, and stirring into cocktails or lemonade.

Ingredients for Making Rhubarb Syrup

Sugar: Granulated (white) sugar is our pick for this recipe as it has the most neutral flavor, dissolves easily, and lets the flavor of the rhubarb shine through. If desired, you can use a less refined sugar like demerara, but the color of the syrup will be darker and the flavor a bit richer.

Rhubarb: You'll need six ounces of rhubarb, or about three medium-sized stalks, for this recipe. When shopping for rhubarb, look for shiny, firm stalks free of blemishes. Color is not an indicator of sweetness, so feel free to grab whatever looks best, whether bright green, pink, or deep red.

Vanilla: If you can obtain a vanilla bean for this recipe, it will give the syrup the best, most pure vanilla flavor. You can easily swap in a teaspoon of vanilla extract or vanilla bean paste instead, just do it after the mixture has come off the heat to avoid cooking off the vanilla flavor.

How to Make Rhubarb Syrup In 3 Easy Steps

Chop: To get your rhubarb ready for this recipe, rinse it well, then trim and discard any leaves that may still be attached—they contain a toxic compound that can be harmful to humans and animals if consumed. Chop rhubarb into small, quarter-inch pieces, which will help it cook down more quickly and release the most flavor.

Simmer: Once your rhubarb is prepped, you'll combine it and the remaining ingredients in a medium saucepan, then bring it up to a boil over high heat, stirring or whisking constantly to dissolve sugar. Once it reaches a boil, let it cook until rhubarb is fully tender, which should only take a few minutes.

Strain and cool: Before your syrup is ready to use, you'll want to remove the cooked-down pieces of rhubarb as well as the vanilla bean. If you have a fine-mesh strainer, place it over a clean, heatproof bowl and pour the syrup through it. (A double layer of cheesecloth set over a bowl will work just as well here.) Let the syrup cool completely, then transfer it to a jar or bottle and refrigerate until you're ready to use it.

Think twice before tossing the cooked rhubarb and vanilla bean. You can reserve the rhubarb for spooning over yogurt or ice cream. The vanilla bean can be rinsed and dried, then tucked into a container of sugar for homemade vanilla sugar or popped into a bottle of vodka for a subtle infusion. It won't have the same punch as if you'd used a fresh pod, but it still contains quite a bit of flavor and is worth hanging onto.
