Radishes are an edible root vegetable. They come in a variety of colors, with the most common being red and white. The root of the radish is crisp and has a sharp peppery flavour, with some radish varieties being hotter than others.
Radishes are most commonly used in salads, and can be preserved by pickling them. Radish leaves and seeds are also edible but not as many people eat them as eat the root.
