A radish is a root vegetable that belongs to the Brassicaceae family, which also includes mustard and cabbage. It has a long history dating back to ancient times when it was first cultivated in Asia. Radishes come in various shapes, sizes, colors, and flavors ranging from mild to spicy. They are typically eaten raw as a crunchy snack or used in salads, but can also be cooked and added to dishes for extra flavor.
