Interesting. Never thought to try that. I always freeze it or use it up as the season goes...
How to Use Dried Rhubarb?
Dehydrated rhubarb can never be turned back into juicy, fresh rhubarb. It will plump up when soaked in water, but it will have a slightly chewy texture. So use dried rhubarb in recipes where a little added texture is appreciated, e.g. muffins, oatmeal, pancakes, cookies, etc. The longer it cooks or stews in liquid, the less chewy it becomes, so you could also use it in sauces – rhubarb sauce on pork chops perhaps?

Thanks for the helpful link. I think I am going to dehydrate some and then see if I can grind it into a powder. Maybe add it to recipes that could use a little tartness, like muffins. I don’t know. Fingers crossed. I can find rhubarb in the store here in SE Texas but it’s kind of expensive so it’s not at the top of my shopping list so this little experiment will not happen right away.
Sounds absolutely delicious!
