Seem or sim is a vegetable that is widely known in the Asias. They are a close relative of the snow peas. In fact, they look very much like snow peas but are just thicker, darker and longer. The flavor also is similar but instead of the sweetness that snow peas have, seem have a sharp yet mellow flavor. Sim er bichi can be bought at any bangali grocery store. If not available though, it can be substituted with lima beans and the taste wouldn't change drastically.
