Why Make Unsweetened Rhubarb Juice?

I make this juice to extend the repertoire of dishes that I can make using rhubarb.  After baking several batches of rhubarb muffins, rhubarb pie and rhubarb crisp – I’m ready for something a little different.  This juice makes it easy to create new recipes like Honey Rhubarb Sesame Chicken, Rhubarb Poppyseed Dressing, luscious rhubarb bars (coming soon), cocktails, mocktails and other dishes.
