(Makes about 1½ cups)
- 4 stalks of rhubarb (about 4 cups, chopped )
- 1 apple , cored and cut into chunks
- ½ cup honey (adjust to taste )
- 2 teaspoons vanilla extract
- ¼–½ teaspoon cinnamon (adjust to taste )
- Optional : A pinch of nutmeg or cloves for extra warmth
Step-by-Step Instructions
Step 1: Prep the Ingredients
- Wash and chop the rhubarb into small pieces (discard any leaves, as they are toxic).
- Core and chop the apple into chunks—no need to peel unless you prefer a smoother texture.
Step 2: Simmer the Mixture
-
- In a medium saucepan, combine the chopped rhubarb , apple chunks , and honey . Stir to coat the fruit evenly with the honey.

- Cook over medium heat, stirring occasionally, until the fruit softens and breaks down (about 15–20 minutes ).
- Tip : If the mixture starts to stick, add a splash of water or apple juice to loosen it.
Step 3: Blend Until Smooth
- Once the fruit is soft and mushy, remove the pan from the heat and let it cool slightly.
- Use an immersion blender to puree the mixture until smooth.
- Alternative : Transfer the mixture to a regular blender and blend until smooth. Be careful when blending hot liquids—work in batches and vent the lid.
Step 4: Add Flavorings
- Stir in the vanilla extract and cinnamon . Taste and adjust the sweetness or spice level as needed.
- Optional : Add a pinch of nutmeg or cloves for a deeper flavor profile.
Step 5: Thicken the Butter
- Return the pureed mixture to the saucepan and cook over low heat, stirring frequently, until it thickens to your desired consistency (about 10–15 minutes ).
-
- Tip : To test thickness, place a spoonful on a plate—if it holds its shape without spreading too much, it’s ready.

Step 6: Store or Serve
- Let the rhubarb butter cool completely before transferring it to a clean jar or airtight container.
- Store in the refrigerator for up to 2 weeks or freeze for longer storage (up to 6 months ).
