How to Make Sweet Tangy Rhubarb Butter (Print version)

A smooth, sweet tangy rhubarb butter made with fresh rhubarb, lemon, sugar, and vanilla for toast, yogurt, biscuits, and desserts.

# Ingredients:

For the rhubarb butter

01 - 2 lb (900 g) fresh rhubarb stalks, leaves removed, cut into 1-inch pieces
02 - 3/4 cup (150 g) granulated sugar, plus more to taste
03 - 2 tablespoons fresh lemon juice
04 - 1/4 cup (60 ml) water, or 2 tablespoons if using frozen rhubarb
05 - 1/8 teaspoon fine salt
06 - 1 teaspoon vanilla extract

# Instructions:

01 - Trim the rhubarb ends, discard all leaves, rinse the stalks well, and cut them into 1-inch pieces.
02 - Add rhubarb, sugar, lemon juice, water, and salt to a wide heavy-bottomed pot. Cook over medium heat until bubbling, then reduce to medium-low and simmer for 12-15 minutes until the rhubarb breaks down.
03 - Remove the pot from the heat. Blend with an immersion blender until smooth, or carefully transfer the hot mixture to a blender in batches.
04 - Return the puree to medium-low heat. Simmer for 20-25 minutes, stirring often, until glossy and thick enough that a spoon leaves a brief trail across the bottom of the pot.
05 - Stir in the vanilla. Taste and add a little more sugar for sweetness or lemon juice for brightness if needed.
06 - Spoon the rhubarb butter into clean jars. Cool, cover, and refrigerate for up to 2 weeks or freeze for up to 6 months.

# Good to know:

01 - Makes about 3 cups, depending on how far you reduce it.
02 - This recipe is for refrigerator or freezer storage, not shelf-stable canning.
03 - Frozen rhubarb works well but may need a few extra minutes to reduce.
