Step‑by‑Step Instructions for Refreshing Rhubarb Lemonade Concentrate
Step 1: Prepare Rhubarb
Begin by carefully washing 4 cups of fresh rhubarb stalks under cool water to remove any dirt. Chop them into 1/2″ pieces, discarding any leaves as they are toxic. You can use frozen rhubarb if fresh isn’t available; just measure out the equivalent amount. Set aside the prepared rhubarb for the next step.
Step 2: Prepare Lemons
Next, zest and juice about 4 large lemons, aiming to yield roughly 1 cup of fresh juice. Use a zester or fine grater to remove only the yellow outer layer, avoiding the bitter white pith. Strain the lemon juice through a fine mesh sieve to catch any seeds or pulp, ensuring your Rhubarb Lemonade Concentrate is smooth and refreshing.
Step 3: Cook the Mixture
In a medium-sized saucepan, combine 4 cups of water, 2 cups of granulated sugar, the chopped rhubarb, and the prepared lemon juice and zest. Place the saucepan over medium-high heat and bring the mixture to a boil. Allow it to simmer for about 20 minutes, stirring occasionally, until the rhubarb becomes tender and breaks down visually when stirred.
Step 4: Mash & Strain
After cooking, remove the saucepan from heat and take a potato masher to gently mash the softened rhubarb further, releasing all that tangy goodness. Let the mixture cool for about 10 minutes, then carefully strain it through a fine mesh strainer into a large bowl. This will separate the liquid concentrate from any solids, ensuring a smooth finish.
Step 5: Store & Serve
Transfer the finished Rhubarb Lemonade Concentrate into clean jars or bottles. Seal tightly and store in the refrigerator for up to 5 days. When ready to enjoy, mix the concentrate with water in a 3:1 ratio—3 cups of water to 1 cup of concentrate—for a delightful, refreshing drink. If you fancy something fizzier, try using soda instead of water!
