Siman: 203, Seif: 08

If you don't take it off the stalk, it'll become rock hard; you won't be able to eat it. If it's a tznon (radish), you have to pick it at the right time. If you leave it on the plant, it becomes a tree. Some say that today, our tznon that are very bitter, we don't eat except with bread because it's very hard to eat it alone. They want to say it goes down to a Shehakol (by whose word all things exist). The law of Yaakov is that instead of eating it with bread, you eat it with a Shehakol.
