How to make rhubarb butter
Wash the rhubarb thoroughly.
Slice off the broad green leaves and the ends of the stalks. Place the rhubarb stalks in a colander or grip a bunch loosely in one hand and run them under a stream of cool water.
Scrub off any visible dirt and remove damaged or discolored spots with a paring knife. Fresh rhubarb can be found seasonally (late spring to early summer) at most supermarkets and specialty food stores.
