Add all the ingredients to the slow cooker, gently folding the ingredients until thoroughly mixed.

With a clean dishtowel, wipe the rims of the jars. Add warmed lids and rings to finger tight.
Process the strawberry rhubarb butter in a steam canner or hot water bath canner based on your altitude, see the processing times below.

Pro Tips for Perfect Rhubarb Butter

Here are a few tips to ensure your strawberry rhubarb butter turns out perfectly every time:

Use Fresh, High-Quality Ingredients: The flavor of your butter will only be as good as the ingredients you use. Opt for ripe, in season strawberries and firm, vibrant rhubarb.
Don’t Overblend: Blending too much can result in a gummy texture. Blend just until smooth.
Adjust Sweetness to Taste: Rhubarb can be quite tart, so adjust the amount of sugar to your liking. Taste the mixture as it cooks and add more sugar if needed.
Proper Headspace is Key: Leaving the correct amount of headspace in your jars is crucial for safe canning.
Check Seals: After processing, check that each jar has sealed properly. The lid should be concave and not flex when pressed.

Common Mistakes to Avoid

Even with a simple recipe, mistakes can happen. Here’s what to watch out for:

Not Stirring Frequently Enough: This can cause the sugar to burn and stick to the bottom of the slow cooker.
Overcooking: Overcooking can result in a dry, caramelized butter.
Using Old or Damaged Jars: Always use new or sterilized jars in good condition for canning.
Skipping the Water Bath: This step is essential for long-term storage and preventing spoilage. It ensures the product is shelf stable.

Strawberry Rhubarb Butter Variations

Want to add a little twist? Here are some delicious variations to try:

Spiced Rhubarb Butter: Add a pinch of cinnamon, nutmeg, or cloves for a warm, comforting flavor.
Ginger Rhubarb Butter: A teaspoon of grated fresh ginger adds a zesty kick.
Lemon Rhubarb Butter: Add the zest and juice of one lemon for a bright, citrusy flavor.
Honey Rhubarb Butter: Replace some of the granulated sugar with honey for a more complex sweetness.

Processing Times for Canning Strawberry Rhubarb Butter

When preserving your homemade strawberry rhubarb butter, it’s essential to follow proper canning procedures to ensure a safe and shelf-stable product. Processing times vary based on altitude and the type of canner you are using.

Hot Water Bath Canning

A hot water bath canner is a traditional method for preserving high-acid foods like fruit butters. Ensure your jars are fully submerged in boiling water throughout the processing time.

Altitude Adjustments:

0 – 1,000 feet: 10 minutes
1,001 – 6,000 feet: 15 minutes
Above 6,000 feet: 20 minutes

Steam Canning

Steam canning is another option for preserving strawberry rhubarb butter. This method uses less water than a hot water bath and can be more energy-efficient.

Altitude Adjustments: Follow the same altitude adjustments as with hot water bath canning.

Important Note: Always consult your canner’s instruction manual and a reliable canning resource (such as the National Center for Home Food Preservation) for the most accurate and up-to-date processing times and safety guidelines.

By following these guidelines, you can ensure that your strawberry rhubarb butter is safely preserved and ready to enjoy throughout the year. Enjoy the fruits (and vegetables!) of your labor!
