Rhubarb Butter: A Taste of Spring Sunshine

The first bite of rhubarb always transports me back to my grandmother’s garden. I can almost feel the slightly prickly leaves brushing against my legs as I reached for the crimson stalks, their tartness a delightful promise. She would always make a big batch of rhubarb butter, the scent of cinnamon and simmering fruit filling her cozy kitchen. It was a simple pleasure, spread thick on warm toast, a reminder that even the most unassuming ingredients can be transformed into something truly special.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 25 minutes
• Total Time: 40 minutes
• Yields: 3 1/2 pints
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 6 cups rhubarb, cut into 1-inch chunks
• 1/2 cup water
• 2 1/2 cups sugar
• 1 teaspoon cinnamon
• 4 drops red food coloring (optional)

Equipment Needed

• Blender or food processor
• Heavy-bottomed saucepan
• Wooden spoon or spatula
• Ladle
• Hot, sterilized jars
• Hot water bath canning equipment

Instructions

1. Begin by preparing your rhubarb. Wash the rhubarb stalks thoroughly. Using a sharp knife, trim off the ends and cut the rhubarb into approximately 1-inch chunks. Uniformity in size will help ensure even cooking.

2. In a blender or food processor, combine the chopped rhubarb with the water. Blend until you achieve a smooth pulp. You should end up with about 3 cups of rhubarb pulp. This step is crucial for creating the right consistency for your butter.

3. Transfer the rhubarb pulp to a heavy-bottomed saucepan. The heavy bottom is important to prevent scorching as the mixture cooks down. Place the saucepan over medium-high heat and bring the rhubarb pulp to a boil, stirring frequently to prevent sticking.

4. Once boiling, reduce the heat to medium. Add the sugar and cinnamon to the saucepan. Stir constantly to ensure the sugar dissolves completely and is evenly distributed throughout the rhubarb pulp. The cinnamon adds a warm, aromatic note that complements the tartness of the rhubarb.

5. Continue to cook the mixture, stirring constantly, until it thickens and resembles fruit butter. This process typically takes about 20-25 minutes. The mixture will gradually darken and become more viscous as the rhubarb breaks down and the sugar caramelizes slightly. To test for doneness, place a small spoonful of the rhubarb mixture on a chilled plate. If it sets up quickly and doesn’t run, it’s ready.

6. (Optional) If desired, add up to 4 drops of red food coloring to enhance the color of the rhubarb butter. This step is purely aesthetic; the food coloring does not affect the flavor or texture of the butter. Stir well to incorporate the color evenly.

7. Carefully ladle the hot rhubarb butter into hot, sterilized jars, leaving about 1/4-inch headspace at the top of each jar. Wipe the rims of the jars clean with a damp cloth to ensure a good seal. Place the lids on the jars and screw the bands on fingertip-tight.

8. Process the filled jars in a hot water bath (212 degrees Fahrenheit) for 5 minutes. Ensure the jars are fully submerged in the boiling water. The hot water bath canning process creates a vacuum seal, which preserves the rhubarb butter and prevents spoilage.

9. Using a jar lifter, carefully remove the jars from the hot water bath and place them on a clean towel-lined surface to cool. Avoid tilting the jars during this process. As the jars cool, you should hear a “popping” sound as the lids seal. This indicates that a vacuum has formed inside the jar.

10. Once the jars are completely cool, check the seals by pressing down on the center of each lid. If the lid doesn’t flex or pop back up, it’s properly sealed. If a lid doesn’t seal, refrigerate that jar of rhubarb butter and use it within a week.

Expert Tips & Tricks

• Rhubarb Variety: The color of your rhubarb stalks will affect the final color of your butter. Redder stalks will produce a more vibrant butter.
• Sugar Adjustment: Adjust the amount of sugar to your liking, depending on the tartness of your rhubarb and your personal preference. You can also experiment with other sweeteners like honey or maple syrup.
• Spice it Up: Feel free to experiment with other spices like ginger, nutmeg, or cloves. A pinch of cardamom can also add a unique flavor.
• Thickening Issues: If your rhubarb butter seems too thin after cooking, you can add a tablespoon of cornstarch mixed with a little cold water to the saucepan during the last few minutes of cooking. Stir constantly until the mixture thickens.

Serving & Storage Suggestions

Rhubarb butter is incredibly versatile. Spread it on toast, biscuits, scones, or muffins for a delightful breakfast or snack. It’s also delicious as a filling for cakes, pastries, or crepes. Try it as a glaze for grilled chicken or pork for a sweet and tangy twist.

Properly sealed jars of rhubarb butter can be stored in a cool, dark place for up to a year. Once opened, refrigerate the butter and use it within a few weeks.
