Trim and chop 2 lbs fresh rhubarb into 1-inch pieces. This ensures even cooking and optimal texture for your Best Rhubarb Butter Recipe. Set aside the prepared rhubarb.

In a large heavy-bottomed pot, combine the chopped rhubarb, 1 cup granulated sugar, 1/2 cup packed light brown sugar, 2 tbsp fresh lemon juice, 1 tsp ground cinnamon, 1/2 tsp ground ginger, 1/4 tsp ground nutmeg, 1/4 tsp fine sea salt, and a pinch of ground cloves.

Bring the mixture to a boil over medium-high heat, then reduce heat to low. Cover and simmer for 15-20 minutes, stirring occasionally, until the rhubarb is very soft and easily mashed. This creates the flavorful base.

Carefully transfer the cooked rhubarb mixture to a blender or use an immersion blender directly in the pot. Process until completely smooth. For the creamiest Best Rhubarb Butter Recipe, ensure no large chunks remain.

Return the pureed rhubarb to the pot (if transferred). Stir in 2 tbsp unsalted butter, 1 tsp pure vanilla extract, and 1 tsp orange zest until the butter is fully melted and incorporated, enriching the flavor profile.

Continue to simmer the rhubarb butter over low heat, stirring frequently, for another 15-20 minutes, or until it reaches your desired thickness. It will thicken further as it cools. This completes your Best Rhubarb Butter Recipe.
