A tart and sweet spread made from fresh rhubarb, perfect for toasts and pastries.

Ingredients

Scale
  • 1 pound fresh rhubarb, trimmed and chopped into 1/2-inch pieces
  • 1/2 to 3/4 cup granulated sugar
  • 1 to 2 tablespoons fresh lemon juice

Instructions

  1. Wash and trim the rhubarb. Chop into even pieces so it cooks uniformly.
  2. Combine the rhubarb, sugar, and lemon juice in a medium saucepan over low to medium heat. Stir to coat the fruit in sugar.
  3. Bring to a gentle simmer. Cook uncovered, stirring every few minutes to prevent sticking, until the rhubarb has collapsed and the liquid has reduced, about 15 to 25 minutes.
  4. Test for thickness by spooning a small amount onto a chilled plate; it should hold together and not run. If it’s still watery, simmer a few minutes longer.
  5. Remove from the heat and let the mixture cool slightly. Use an immersion blender or transfer to a countertop blender. Purée until completely smooth and silky.
  6. Spoon the warm rhubarb butter into clean jars. Let cool to room temperature, then refrigerate.

Notes

For a thinner spread, reduce cooking time slightly; for a thicker butter, simmer until more water has cooked off. If using frozen rhubarb, thaw and drain excess liquid before cooking.
