A simple and tangy fruit sauce, similar to applesauce, that
you can eat on ice cream, yogurt, toast, or just plain by itself.
Add all of the ingredients to a medium saucepan, and bring
to a boil. Reduce heat to a simmer, and simmer for approximately 20 minutes, or
until the rhubarb chunks have broken down and the sauce has a smooth, silky
consistency. If the sauce looks too watery, continue simmering until the sauce
thickens to your taste.
