The Easy Hack To Bring Weary Cucumbers Back To Life
By Crystal Antonace
Cucumbers actually have quite a long shelf life when kept intact. Whole cucumbers can last up to two weeks in the right environment, while sliced cucumbers only last a few days.
If your old whole cucumbers are bendable and soft, slice them into spears, pack them tightly in a jar, and add water to completely cover them before refrigerating for 12 hours.
Cucumbers are over 90% water, so osmosis causes their inner cells to retain water and push against the outer skin, keeping them crisp and firm — this is called turgor pressure.
To keep cucumbers fresh from the beginning, store them upright in your refrigerator, ideally in the crisper drawer, with a protective layer like plastic wrap to seal in moisture.
