Slow Cooker Rhubarb Butter

Step 1

Add all ingredients into the slow cooker. (You can also use an Instant Pot for this recipe; see Notes.)

Step 2

Cover and leave on HIGH for 1 hour.

Step 3

Transfer contents to a blender and blend until very smooth. (I use my Blendtec on Smoothie mode, which is perfect for this.)

Step 4

Pour blended mixture back into slow cooker.

Step 5

Leave on LOW for 6 hours. Do not cover.

Step 6

When desired consistency is reached, stir the mixture well before pouring into jar for storage.
