Combine 2 lbs fresh rhubarb (trimmed and chopped into 1-inch pieces) and 1/4 cup water in a large saucepan. Bring to a simmer over medium heat, then reduce heat to low. Cover and cook for 10-15 minutes, or until the rhubarb is very soft and broken down. This forms the tangy core of your Best Rhubarb Butter Recipe.

Uncover the saucepan. Stir in 1 1/2 cups granulated sugar, 1/4 cup light brown sugar (packed), 1/2 cup (1 stick) unsalted butter (cut into pieces), 1/2 tsp ground cinnamon, 1/4 tsp ground ginger, 1/8 tsp ground nutmeg, and a pinch of salt. Mix well to combine all ingredients.

Increase heat to medium-low and bring the mixture to a gentle simmer, stirring frequently until the sugars dissolve and butter melts. Continue to cook, stirring occasionally, for 25-30 minutes, or until the rhubarb butter thickens to your desired consistency. This creates the sweet, tangy & creamy texture.

Carefully transfer the hot rhubarb mixture to a blender or use an immersion blender directly in the pot. Blend until completely smooth and creamy. Be cautious when blending hot liquids; vent the blender lid if using a traditional blender to release steam.

Return the blended rhubarb butter to the saucepan (if transferred). Stir in 1 tsp pure vanilla extract, zest of 1 large lemon, and 2 tbsp fresh lemon juice. Cook for another 2-3 minutes over low heat, allowing these aromatic brighteners to meld into your Best Rhubarb Butter Recipe.
