Add rhubarb, water, and sugar to a pot over medium heat on the stove.
2 cups Rhubarb, ½ cup water, ½ cup granulated sugar
The sugar will begin to melt and the rhubarb will start to soften.
Once the water reaches a low boil and the rhubarb is soft to the touch with a spoon, remove it from the heat.
Mix in the lemon juice.
½ teaspoon lemon juice
Add the mixture to a blender and blend until smooth. Let it cool before serving!
Notes
I like to use an emulsion blender to blend my sauce.
If you want it slightly chunkier, you can blend it a little less.
I find lemon juice adds an amazing flavor to rhubarb sauce. However, later in the year, I sometimes like to swap it out for a little bit of cinnamon or cardamom to pair with apple desserts.
If you have leftover sliced rhubarb, you can freeze it to use again later. Add it to a freezer-safe bag or container and label with the date. Freeze for up to 1 year.
