Daikon, also known as a Chinese radish, is a winter radish with mild flavor.
Furikake, a Japanese rice seasoning, adds subtle taste and texture to this salad. To make your own furikake, crumble 1 sheet of nori (toasted seaweed used to wrap sushi) and toss with 2 tsp. toasted sesame seeds and 1/4 tsp. sea salt.
