I found this pretty radish today. It looked very plain and ordinary on the outside. White and greenish.
But with a magenta heart inside!
It is a watermelon radish. Peppery and strong! Very pretty in bento :) Recipetips says you can use it as you would a regular radish, and that it may also be referred to a Beauty Heart, Rose Heart, Shinrimei, Misato, Asian Red Meat, or Xin Li Mei radish. I used it as an accent detail with side veggies in a recent bento, and I think it would also be good in a salad. Perhaps you can find it in your market and try it yourself :)
