In order to extract juice from rhubarb, you have to cook it down and strain it. The mash doesn’t look pretty, but the juice is a lovely light pink/coral color.

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.

How to Make Rhubarb Concentrate

It’s pretty straight forward:

• pick 8-10 stalks of rhubarb
• wash and chop
• add to large pot and enough water to cover bottom by 1/2 inch
• cook 10-15 minutes until rhubarb is broken down
• strain and collect the juice
• compost the leftover pulp
