Instructions
- Wash and hull the strawberries, removing all green stems. Place them in a food processor or blender and puree until completely smooth.
- Pour the strawberry puree into a slow cooker. Stir in the honey, granulated sugar, lemon juice, and salt until the sugar is mostly dissolved.
- Set the slow cooker to LOW. Place the lid on top but prop it open slightly with a heat-resistant wooden spoon to allow steam to escape, which helps the mixture thicken.
- Cook on LOW for 8 to 10 hours (or HIGH for 4 to 5 hours), stirring occasionally to prevent sticking at the edges. The butter is ready when it is thick, dark, and holds its shape on a spoon.
- Turn off the slow cooker and stir in the vanilla extract. Let the mixture cool to room temperature.
- Transfer the strawberry butter to airtight jars and store in the refrigerator for up to 1 week or freeze for up to 6 months.
Notes
Propping the lid open is the secret to getting a thick consistency in the slow cooker. If you prefer a seedless butter, strain the puree through a fine-mesh sieve before adding it to the slow cooker.
