It's most likely the greens that smell bad. You should buy those baggies they sell in some food stores that help keep your veggies/fruits good for longer by absorbing the gases that make them break down quicker. I had my daikon in the fridge for a week - and the greens smelled gross - but the part you eat was fine when cooked.
Mine didn't have the greens on it so I don't know. Today I cut a piece off and graded it. I left it out on the counter, I thought maybe the fridge doesn't agree with it.
I got mine at the farmers market (two for a dollar!). It is long an white....looks like a huge white carrot. They usually have it in the grocery store near the fresh ginger and cabbage and raddish. Google it and click on images.
ya sabrina - i bought mine yesterday at a green grocer in town and mine was a tad wobbily and soft-ish. but they 'just' brought em in (three days prior they didn't have any daikon, so i'm guessing its fresh-ish).
have yet to grate it and eat it though - am stoked to do so.
I wasn't sure about the daikon when I came across at the grocery store the other day. It felt a bit soft and wobbily like peas and carrots said. So, I didn't get it, but now I'm thinking maybe it's supposed to feel that way?
Evie - it's kind of like a white carrot, but some of them can look pretty long and thick.
