Sabrina’s Rhubarb Sauce Recipe
Rhubarb has a bold, sour flavor that is also slightly sweet, apple flavor. Often you’ll find it paired with strawberry to balance out the tart flavor but with some simple ingredients to sweeten it up, you can also get that delicious rhubarb flavor shine on it’s own. For my easy Rhubarb Sauce, you’ll cook together rhubarb, sugar, lemon juice, and water on the stovetop. Then, blend it all into a simple sauce perfect for frozen desserts, cakes, Pancakes, and more.
My Rhubarb Sauce recipe works by breaking down the rhubarb and sugar ingredients. As you cook the rhubarb, the vegetable will soften and release natural juices. Meanwhile, the sugar will melt and mix with the rhubarb. The vegetable’s bitter flavor will also start to mellow during this process. Once it mixes with the sugar and lemon juice, you’ll have a tasty balance of sweet and sour flavor.

Ingredients
- 4 Cups Fresh Rhubarb Slices: The main ingredient in Rhubarb Sauce is fresh rhubarb. Before starting the recipe, rinse the rhubarb under cold water and trim tough, woody parts off of the bottom of the stocks. Be sure to throw out the rhubarb leaves as they are toxic. You can also slice the rhubarb into 1-inch pieces to make them easier to cook down.
- 3 Tablespoons Lemon Juice: The citric acid in the lemon juice helps highlight the natural rhubarb flavor and enhances the sweetness of the sauce.
- 2 Cups Sugar: Make the tart rhubarb flavor more enjoyable by counteracting it with granulated sugar. As the rhubarb and sugar cook, they’ll start to blend into a rich, syrupy sauce.
- 2 Cups Water: Add cooking liquid to help cook and soften the sauce ingredients. As the recipe cooks, the liquid will reduce slightly but still helps to smooth out the sauce recipe.

Kitchen Tools & Equipment

- Spoon: Use a wooden spoon to stir and help break down the Rhubarb Sauce as it cooks.
- Blender: To break down the rhubarb pieces into a smooth sauce, use a high-power blender or food processor and blend until pureed. An immersion blender would also do the job, just make sure you get all the lumps blended out.

Cooking Rhubarb Sauce Tips & Tricks
Remember these recipe tips to make perfectly flavored and smooth Rhubarb Sauce.

- Rhubarb is quite bitter on its own, which is why it’s important to add sugar to make the sauce more enjoyable. Depending on how ripe the rhubarb you’re using is, the recipe may turn out more or less bitter. Taste test after adding the sugar, and add a little more as needed to taste.
- Thicken the Sauce
- If you’re Rhubarb Sauce is turning out too watery, you can continue to cook until the liquid reduces. If it still seems thin to you, try mixing cornstarch and water into a cornstarch slurry and adding a little to the sauce mixture to thicken it.

Frequently Asked Questions
There’s no need to peel your rhubarb. However, it is essential to remove the leaves, which are toxic. Then, slice off the tough root portion.
Because rhubarb has a naturally bitter and tart flavor, this sauce is unpleasant tasting without a sweetening ingredient. However, you can try other ingredients like coconut sugar, agave nectar, or honey to sweeten the mixture instead of sugar. To reduce the amount of sweetener needed, you can also add sweeter fruits like strawberries to the rhubarb mixture. This will just change the flavor of the recipe.
