Cut the rhubarb into small pieces (about 1-inch long) and lay them in one layer on a baking sheet. Put the baking sheet in the freezer and wait until rhubarb is frozen–a few hours. Remove baking sheet and pack rhubarb into freezer safe zip-close bags. If you are storing rhubarb for more than a few months, you will need to blanch it before freezing.
