About this Strawberry Rhubarb Syrup recipe

I always get excited when I see rhubarb on the tables of the farmer’s market or the shelves at the grocery store. It means that spring has arrived, and this sweet-tart veggie is ready for the season.

Paired with strawberries, rhubarb adds an earthy, tart and delicious flavor. This classic flavor pairing is often baked into pies and desserts, but it is absolutely wonderful mixed into drinks too. Just take this sparkling strawberry rhubarb cocktail for example.

The easiest way is with a simple syrup. Stew strawberries and rhubarb together on the stove, then mix the remaining liquid with sugar to make a syrup you can mix into cocktails, mocktails, lemonade and even tea drinks. Bakers sometimes brush it onto cakes to keep them moist. Plus it lasts for a while in the fridge.

You only need four ingredients to make this simple syrup. First, you’ll simmer together strawberries and rhubarb in water, which will help to extract the juices, essential oils and flavors from the produce. If you cannot locate fresh rhubarb, you can use frozen! The same goes for strawberries — feel free to use frozen berries instead of fresh.

You can make the syrup with just strawberries or just rhubarb if you prefer, or mix in other kinds of fruit and berries like blueberries, blackberries or even cherries. But the soft sweetness of strawberries is a perfect match for sour rhubarb, so I recommend you try it this way before you customize!

Once everything has softened and simmered down, you’ll strain the liquid and mix it with granulated sugar to make the simple syrup. Use any kind of sugar or sweetener that you like. Just keep in mind that anything brown, like brown sugar or honey, may change the color of the syrup.

As far as equipment, grab some measuring cups, a saucepan, a sharp knife, a cutting board and a fine-mesh strainer *. A strawberry huller * is nice to have, too. You’ll also need some kind of airtight jar for storing the syrup.

Instructions

This syrup is easy to make on the stove. Slice the strawberries and rhubarb before you begin. It’s totally fine to use frozen strawberries or frozen rhubarb, or combine one fresh and one frozen. No need to thaw before you begin because all the melted liquid will go perfectly in the syrup.

Tips & tricks

  • Use a fine-mesh strainer, not a colander, so that no solids from the cooked-down fruit escape into the syrup.
  • For the best balance, measure the liquid that you get from the syrup. Then add the same amount of sugar for a 1:1 ratio. You can add up to twice as much sugar (a 2:1 ratio), which will yield a sweeter, thicker syrup.
  • Rhubarb’s flavor ranges from sweet to tart. The redder it is, the sweeter; the greener, the more sour. Since you’re adding sugar, it doesn’t matter as much, but if you would prefer less tartness, be sure to grab the reddest stalks.
