Rhubarb has a fruity, mouth-puckering tang. It looks like blushing celery. Like lemon or lime juice, rhubarb boosts other flavors. We like it in chutney served with pork roast. But its most famous use is sweetened and cooked with strawberries in a pie. This classic mixture gives rhubarb its other name, pie plant. As a change of pace from strawberries, try combining rhubarb with orange or ginger.
