Rhubarb is a stem, not a fruit, but it is used like a fruit. Buy firm, crisp, tender rhubarb with thick stalks, not thin and shriveled.
Cut off all traces of leaf, which is poisonous. Trim the root end, if necessary. Peel with a vegetable peeler, if desired, or omit this step if the skin is tender. Cut into desired lengths.
Percentage yield: 85โ90% (if purchased without leaves)
