 In the United States the common usage of rhubarb in pies has led to it being nicknamed ‘pie plant’, by which it is referred to in many 19th century US cookbooks.Rhubarb in the US is also often paired with strawberries to make strawberry-rhubarb pie, though some rhubarb purists jokingly consider this "a rather unhappy marriage".In former days, a common and affordable sweet for children in parts of the United Kingdom and Sweden was a tender stick of rhubarb, dipped in sugar.
