Step-by-Step Instructions
Step 1: Prepare the Rhubarb
Wash the rhubarb stalks thoroughly and cut them into 1-inch pieces. The skins can be slightly tough, so be sure to trim any discolored sections. Fresh, vibrant rhubarb will yield the best flavor!
Step 2: Combine Ingredients
In a medium saucepan, combine the chopped rhubarb, sugar, water, and lemon juice. Stir to mix the ingredients well, making sure the sugar begins to dissolve.
Step 3: Cook the Mixture
Place the saucepan over medium heat and bring the mixture to a gentle boil. Once boiling, reduce the heat to low and let it simmer for about 10-15 minutes. Stir occasionally, allowing the rhubarb to break down and release its juices.
Step 4: Strain the Syrup
After simmering, remove the saucepan from heat. Using a fine mesh strainer or cheesecloth, strain the mixture into a clean bowl or jar, pressing down to extract as much syrup as possible while leaving the solids behind. Discard the solids or use them in compotes or baked goods!
Step 5: Prepare the Jars
While the syrup is still warm, sterilize your canning jars by placing them in boiling water for about 10 minutes. This step ensures that your syrup stays fresh without spoilage. Allow the jars to air dry or leave them in the hot water until you’re ready to fill them.
Step 6: Can the Syrup
Using a funnel, pour the strained rhubarb syrup into the sterilized jars, leaving about 1/4 inch of headspace at the top. Wipe the rims of the jars with a clean cloth to remove any sticky residue.
Step 7: Seal the Jars
Place sterilized lids onto the jars and tighten the metal rings without over-tightening. Process the jars in a boiling water bath for 10 minutes to ensure proper sealing. Once processed, remove the jars and let them cool completely on a clean towel or cooling rack.
