Cooking Steps

Start your rhubarb cordial journey by collecting vibrant spring stalks and thoroughly sterilizing your glass bottles to safeguard proper preservation.

You’ll need to combine your chopped rhubarb, sugar, water, and aromatics in a large pot, bringing the mixture to a gentle simmer until the stalks break down completely.

Once cooked, strain the liquid through a fine-mesh sieve lined with cheesecloth, let it cool naturally, and finish by stirring in the citric acid solution before bottling your ruby-red cordial.

Step 1. Gather Fresh Spring Rhubarb Stalks

When selecting rhubarb stalks for your cordial, choose bright crimson stems that snap crisply when bent, indicating peak freshness and flavor. You’ll want to inspect stalk quality carefully, looking for firm, unblemished pieces without signs of wilting or spots. The best stalks will have a glossy sheen and feel heavy for their size.

Select prime harvesting time between April and June, when rhubarb’s natural tartness and sugar content are perfectly balanced. You’ll need about 2 pounds of stalks for this recipe, so gather stalks that are roughly 1 to 1.5 inches in diameter. Remember to trim away and discard all leaves, as they’re toxic, and cut off any woody ends at the base. The freshest stalks will yield the most vibrant, flavorful cordial.

Step 2. Prepare Sterilized Glass Containers

Properly sterilized glass bottles serve as essential vessels for preserving your homemade rhubarb cordial’s vibrant flavors and extending its shelf life. You’ll want to select bottles with secure, air tight caps or swing-top closures that guarantee long term storage success.

To sterilize your containers, wash them thoroughly in hot, soapy water, then rinse completely. Place the clean bottles and their lids in a large pot of water, making certain they’re fully submerged. Bring the water to a boil and maintain it for 10 minutes. Using tongs, carefully remove the bottles and place them upside down on a clean kitchen towel to air dry. Let them cool completely before filling with your cordial. For best results, prepare your bottles just before you’re ready to strain and bottle your finished cordial.

Step 3. Combine Ingredients and Boil

Pour your freshly chopped rhubarb and granulated sugar into a large, non-reactive pot, ensuring the rhubarb pieces are evenly coated with sugar. Add the water, freshly squeezed lemon juice, and if you’re using it, split the vanilla pod lengthwise and scrape the seeds into the mixture.

Set your pot over medium-high heat and bring the mixture to a gentle boil, stirring occasionally to help dissolve the sugar. Once boiling, reduce the heat to maintain a steady simmer. You’ll want to keep this simmer duration to exactly 20 minutes – it’s the sweet spot for extracting maximum flavor while preventing any bitter notes from developing. Watch as your rhubarb transforms from crisp pink stalks to tender, pale pieces that release their vibrant essence into the surrounding liquid.

Step 4. Strain Through Fine-Mesh Sieve

After your 20-minute simmer, line a fine-mesh sieve with clean cheesecloth and position it over a large, heat-safe bowl or container. Carefully pour your rhubarb mixture into the prepared sieve, allowing the liquid to drain naturally through the cheesecloth. You’ll notice the gorgeous pink hue of your cordial as it filters through.

Don’t be tempted to press or squeeze the pulp, as this will affect both the strained texture and visual appeal of your final product. The most refined cordials come from patience during this step.

Let the mixture drain completely until the pulp in the cheesecloth stops dripping – this typically takes about 30-45 minutes. When you’re finished, you’ll have a beautifully clear, jewel-toned cordial that’s free from any cloudy residue or unwanted sediment.

Step 5. Add Citric Acid Solution

Once your strained cordial has cooled completely to room temperature, dissolve 2 tablespoons of citric acid into the liquid, stirring gently until the crystals disappear. This citric acid concentration not only enhances the natural tartness of your rhubarb but also acts as a natural preservative, extending the shelf life of your homemade cordial.

You’ll notice the cordial taking on a brighter, more vibrant pink hue as you stir in the citric acid. This transformation indicates that you’ve achieved the perfect balance of sweet and tart flavors that make rhubarb cordial so distinctive. Don’t worry if you see tiny air bubbles forming – they’ll settle as the mixture rests. Once you’ve thoroughly incorporated the citric acid, you’re ready to transfer your cordial to sterilized bottles for storage.

Top Tips

Several essential tips will help you achieve a crystal-clear, perfectly balanced rhubarb cordial. Choose the brightest pink stalks you can find – they’ll create that stunning rosy hue you’re after. For maximum flavor intensity, don’t press down when straining; let gravity do the work to avoid cloudiness.

You’ll get the best results by selecting young, tender stalks in spring when they’re at their peak. To create unique serve ideas, try freezing your cordial with edible flowers in ice cubes, or blend it into sophisticated cocktails. If you’re planning to store your cordial long-term, sterilize your bottles thoroughly and add the full amount of citric acid – it’s not just for taste, it’s a natural preservative. Store your finished cordial in a dark, cool place to maintain its vibrant color.
