Watermelon radishes are an heirloom variety of the daikon radish and are notable for their pale skin and vibrant pink interior, which closely resembles watermelon. The watermelon radish has a subtly sweet flavor with a slight zing of spice and can be enjoyed raw, pickled, or cooked. In fact, thanks to its unique appearance, this type of radish is often used to add a pop of color to rice bowls, salads, or avocado toast.
