If you want more time to enjoy all the cucumbers you bring back from the market, don't stuff them in the fridge. Cucumbers, according to UC Davis via Root Simple, should be stored at room temperature.
The reason, Root Simple explains, is that when cucumbers are stored for over three days at temperatures below 10°C, they'll get cold injury: wateriness, pitting and faster decay. (See how unattractive they look after being stored in the cold in the photo from UC Davis?)
The university also offers lots of other advice for fruit and vegetable storage. While we've covered what and how to store foods in the fridge or counter before, room temperature cucumbers are something we didn't notice before. (You're also supposed to keep tomatoes, peppers, and eggplants out too, but keep the cucumbers away from the ethylene-producing tomatoes!)
