In terms of flavor profiles, most smoothies are very similar; most are based on sweet, fruity flavors sometimes accentuated by dairy.  The  Rhubarb-Citrus Smoothie is a smoothie of an entirely different breed.  This Instructable will demonstrate how to make a Rhubarb-Citrus Smoothie,  an acidic and slightly bitter yet sweet beverage that breaks the norm of docile, bland smoothies that we so regularly enjoy.  Sip one of these smoothies on a hot summer day and it is guaranteed to satisfy.

Juice each of the limes and the lemon by slicing each piece of fruit in half and squeezing it until it relinquishes all of it juices.  Do not worry about pulp or seeds contaminating the juice, we will strain that out later.

Stash the juice in a refrigerator while you prepare the rest of the ingredients.

Note:  If you use a fine quality knife to cut the citrus fruits in half, it is important to wash it as soon as you are finished.  The acidity from the fruit can damage the steel.

Step 3: Rhubarb Juice: Prepare the Rhubarb

The first step towards the creation of your rhubarb juice is to prepare the rhubarb.  First, cut the rhubarb into thin slices and place the slices into a pot.  Using a very sharp knife for this will make the process much easier because the skin on the rhubarb stalks is quite tough and stringy.  The good news is that the skin also contains a lot of flavor, color, and nutrients. 

Second, after all of the rhubarb has been cut and placed into a pot.  Add one cup of the sugar to the pot along with enough water to almost cover the rhubarb.  Give the contents of the pot a stir to ensure that all of the sugar is dissolved.
