Rhubarb butter is a slow-cooked, silky fruit spread made from Rhubarb, known for its naturally tart flavor and vibrant color. Unlike traditional jam, it is fully puréed and reduced into a smooth, concentrated spread that highlights the fruit’s natural tanginess with just enough sweetness for balance.
Ingredients
4 cups fresh rhubarb stalks, chopped (discard leaves—they are toxic)
1 large Apple, cored and chopped (natural pectin source)
1/2 cup Honey or brown sugar
2 teaspoons Vanilla Extract
1/2 teaspoon Cinnamon
Optional: orange zest, juice, or a pinch of ground ginger
Instructions
Wash rhubarb thoroughly and cut into small pieces. Discard leaves completely.
Combine rhubarb, apple, sweetener, and spices in a heavy-bottomed pot.
Bring to a gentle simmer over medium heat, stirring occasionally.
Reduce heat and cook for 20–45 minutes until the fruit fully breaks down and thickens.
Blend using a food mill or blender until completely smooth.
Stir in vanilla extract after cooking for best aroma and flavor.
Cool and transfer to sterilized jars.
How to Make
Slow cooking is key to developing a rich, concentrated flavor.
As the mixture simmers, water evaporates and natural sugars intensify the taste.
The apple helps naturally thicken the spread thanks to its pectin content.
For an ultra-smooth texture, blend thoroughly while still warm before cooling.
Variations
