Capturing Spring: How to Make and Use Rhubarb Cordial
Transform tart rhubarb into a vibrant, versatile cordial for drinks and desserts with this seasonal kitchen project.
Rhubarb Cordial: A Seasonal Celebration in a Glass
Spring brings the eagerly anticipated arrival of rhubarb, that remarkably pink, tart vegetable often mistaken for a fruit. While pies and crumbles are traditional, perhaps the most versatile and visually delightful way to showcase rhubarb is with a homemade rhubarb cordial. This brilliantly hued syrup or liqueur is a revelation—equally at home in fizzy spritzers, cocktails, mocktails, or simply swirled into sparkling water. In this article, we’ll explore how to make rhubarb cordial from scratch, offer serving suggestions, and dive into the little tricks that make the most of this seasonal showstopper.
What Is Rhubarb Cordial?
Rhubarb cordial is a sweet, tart syrup made by steeping rhubarb with sugar (and sometimes citrus or aromatics) and then straining out the solids. It captures the plant’s vivid pink hue and has an intensely refreshing flavor profile, balancing sweetness against the distinctive acidity of rhubarb. Simple to prepare and endlessly adaptable, it’s a perfect kitchen project for spring and early summer, when rhubarb is at its peak.
- Vividly pink and lightly tart
- Can be made as a non-alcoholic syrup or a liqueur with gin or vodka
- Ideal for cocktails, lemonades, spritzers, or pouring over desserts
Why Make Rhubarb Cordial?
Homemade rhubarb cordial harnesses everything that’s irresistible about rhubarb: its spiky tang and bright color. Making your own means you can:
- Capture rhubarb’s fleeting season to enjoy year-round (it freezes beautifully)
- Avoid artificial colors or preservatives
- Adjust sweetness and flavorings to suit your taste
It’s also just plain fun—a kitchen project that feels as rewarding as baking bread but with a much shorter timeline and a show-stopping result.
Choosing and Preparing Rhubarb
The key to a superb cordial is fresh, in-season rhubarb stalks. Look for stalks that are:
- Firm and glossy
- Vividly colored (the pinker, the more vibrant the resulting syrup)
- Free from blemishes or withered ends
Important: Rhubarb leaves are toxic and should always be discarded.
Wash the stalks thoroughly to remove any grit, then trim the ends and slice the stalks into small pieces, about 1/2-inch thick. There’s no need to peel rhubarb; the skin contributes color and flavor.
Anatomy of a Classic Rhubarb Cordial
At its essence, a classic cordial requires only three components:
- Rhubarb – sliced fresh stalks
- Sugar – for sweetness, preservation, and extraction
- Water – to dilute and help dissolve the sugar
Additional ingredients can elevate the profile:
- Citrus zest or juice (lemon, orange, or grapefruit) for brightness
- Ginger for gentle spice
- Aromatics like vanilla bean, hibiscus, or even rose for sophistication
- Alcohol (optional) — for a liqueur-style cordial
The Method: Step-by-Step Rhubarb Cordial
Ingredients
- 6 cups (about 900g) fresh rhubarb, chopped
- 2 cups (400g) granulated sugar
- 3 cups (720ml) water
- Zest and juice from 1 orange (or 2 lemons)
- 1 thumb-sized piece of ginger, finely sliced (optional)
Instructions
- Combine ingredients: Place the rhubarb, sugar, water, citrus zest and juice, and ginger (if using) into a large saucepan. Stir everything together.
- Simmer: Heat over medium, bringing the mixture to a gentle boil. Cook for 15-20 minutes, stirring occasionally, until the rhubarb has completely broken down and the liquid is vividly colored and fragrant.
- Strain: Set a fine-mesh sieve over a large bowl or measuring jug. Pour the contents of the pot through the sieve, without pressing on the solids if you want a clear syrup. For a slightly cloudier cordial with a richer flavor, gently press to extract extra liquid. (Reserve the rhubarb pulp for another use!)
- Taste and adjust: If you’d like it sweeter, return the liquid to the pan, add sugar to taste, and warm gently to dissolve.
- Cool and bottle: Let the cordial cool to room temperature. Pour into clean, sterilized bottles or jars, then seal tightly. Refrigerate for up to two weeks, or freeze for longer storage.
Alcoholic Variation (Optional): Rhubarb Liqueur
- For an adults-only take: macerate sliced rhubarb, sugar, citrus zest, and gin (or vodka) in a large jar for three days. Strain and use as you would classic cordial—for boozy spritzes or cocktails.
What To Do With Rhubarb Pulp?
Don’t toss the leftover, sweet-and-tangy rhubarb pulp! It can be used in several ways:
- Stir into yogurt or porridge
- Spoon onto toast or pancakes
- Incorporate into cakes, muffins, or quick breads
- Whirl into smoothies
Tips and Tricks for Perfect Cordial
- For clearest color: avoid pressing the solids after straining; let gravity do the work for a crystal-clear syrup
- For a thicker syrup: simmer the strained liquid for several minutes to reduce and concentrate before bottling
- To preserve longer: add a small amount of citric acid or freeze in ice cube trays
- Scale up or down: This recipe is flexible—make a large batch if you have a surplus of rhubarb

Recipe FAQ
Q: Can I make rhubarb cordial without sugar?
A: Sugar is essential for extracting the juice and preserving the cordial, but you can reduce the amount or use honey or agave for a milder sweetness. Artificial sweeteners are not recommended for long-term storage.
Q: My cordial isn’t pink—what happened?
A: Color depends on the variety of rhubarb used. Greener varieties yield a paler syrup; using redder stalks and leaving the skin on maximizes color.
Q: How do I sterilize bottles?
A: Wash bottles and lids in hot, soapy water and rinse well. Place them in an oven at 215°F (100°C) for 15 minutes, or run through a dishwasher’s hot cycle. Fill while hot for best results.
Q: Can I make it with frozen rhubarb?
A: Yes! Thaw before using. Frozen rhubarb softens more quickly, speeding up the extraction process.
Q: How do I use rhubarb cordial in baking?
A: Use as a syrup for soaking sponge cakes, or swirl through cheesecakes, frostings, or glazes for bright color and flavor.
Serving Ideas for Every Occasion
- Brunch: Add a splash to mimosas or Bellinis

Troubleshooting and Tips
- Syrup too runny? Simmer uncovered to reduce and thicken
- Too thick? Add hot water, a tablespoon at a time
- Too tart? Add more sugar and heat to dissolve
- Cloudy cordial? Let it settle, or strain again through muslin for clarity
