A carrot-radish pickle is great in a relish tray, or instead of a salad. Also not a bad hot side dish with things like sauerbraten.
Also, radishes can be cooked, and are surprisingly good. https://www.google.com/search?sourceid=chrome-psyapi2&rlz=1C1AVNA_enUS566US566&ion=1&espv=2&ie=UTF-8&q=cooked%20radish%20recipes
Thanks for the link. I never heard of cooking them before. Worth a try for sure.
