Food for Thought
Rhubarb is a species of plant in the family Polygonaceae. They are herbaceous perennials growing from short, thick rhizomes. They have large leaves that are somewhat triangular, with long fleshy petioles. They have small flowers grouped in large compound leafy greenish-white to rose-red inflorescences.
In culinary use, fresh raw petioles (leaf stalks) are crisp (similar to celery) with a strong, tart taste. Most commonly, the plant’s leaf stalks are cooked with sugar and used in pies and other desserts.
Rhubarb is usually considered to be a vegetable; however, in the United States, a New York court decided in 1947 that since it was used in the United States as a fruit, it was to be counted as a fruit for the purposes of regulations and duties. A side effect was a reduction on imported rhubarb tariffs, as tariffs were higher for vegetables than fruits.
Rhubarb can be used as a strong laxative. Its roots have been used as a form of encouragement for at least 5,000 years
In British theatre and early radio drama, the words “rhubarb rhubarb” were repeated for the effect of unintelligible conversation on the background.
