How to combat odor from pickled radishes inside refrigerator? I know the question is related to How to get rid of the smell from the fridge?. At the same time, I am curious about possible additives as part of the pickling that may help reduce the odor. So I didn't use a recipe, but rather finished the jar of pickles found in the Costco chilled section. I thought rather than dumping the remaining solution, I could use the same brine to pickle something. I brought home radishes on sale and just rinsed and cut the tops.

After about 4 days, there was a strong odor which I didn't expect because the original pickles didn't have a smell. I'm assuming it's the radishes that are out of "balance" for this brine solution. Is there something to add to the pickling solution that counteracts radishes?
Since you didn't heat the glass after adding the newly chopped radishes, any bacteria on the radishes weren't killed. The solution (sour and salty) should reduce growth of bacteria, but 
in this case this wasn't enough. Next time remember to heat the picles according to standard pickling instructions.
