Storing peeled cucumber in water is generally better than storing it dry, as it helps prevent dehydration and maintains its crispness.
Peeled cucumbers are highly susceptible to drying out because the protective skin has been removed. When stored dry, even in the refrigerator, they tend to become soft, limp, and less palatable. Submerging the peeled cucumber in water creates a hydrating environment that helps to counteract moisture loss. The water acts as a barrier, preventing the cucumber from drying out and maintaining its turgidity. To store a peeled cucumber in water, place it in an airtight container or a resealable bag filled with water, ensuring the cucumber is fully submerged. Change the water every day or two to keep it fresh and prevent bacterial growth. This method will help keep your peeled cucumber crisp and fresh for a few days.
If you don't want to submerge the entire cucumber, wrapping it tightly in a damp paper towel before placing it in a sealed container can also help retain moisture, though it's generally less effective than submerging it in water.
