A few weeks ago I tried watermelon radish (and actualy said out loud "oh this is a funny radish, it looks like a watermelon"). My friend L. said I was right, that is was actually CALLED a watermelon radish.
Almost immediately I went to my favorite food coop to buy some. There was actually a sticker "watermelon radish". My friend was right !
(I will never doubt anything that I'm told after I spent 2 years not believing my colleague who said he dipped his cheese in his morning coffee. One day I saw him casually dipping his cheese AND his saucisson and I immediately regretted not having trusted a single thing he told me for all this time.)
But that's not the end of the story. The sticker did not match the radish. I actually bought "Sun artichokes" (that kind of look like a sun inside. Or a potato. Not at all like an actual artichoke).
I still don't know what a watermelon radish looks like from the outside. And I won't cut in half all the roots section of the coop.
