Refrigerator: 1 week
Tip: You can also pickle the radishes to keep them for longer.
Washing your radishes and storing them layered with paper towels will keep them fresh and crispy for over a week. Scrub the radishes and then rinse thoroughly in cold water. Get a large jar or a large zipped plastic bag. Line the bottom with paper towel, place damp radishes on top, then continue adding layers of paper towel and radishes. Squeeze out excess air (if using a bag) and then place in the fridge.
