Cucumbers' texture can be improved by soaking them in salt water to help draw out extra wetness. Cucumbers release moisture when they are cut or diced, making them soggy and changing the texture of the food they are added to.
Cucumbers can be made more solid and crisp by soaking them in salt water, which takes out some of the moisture. This can help to ensure that the cucumber maintains its texture and doesn't turn mushy or watery, which is particularly useful when making cucumber salads or other dishes that call for crisp cucumber.
Additionally, adding a saline and faintly tangy flavor to cucumbers by soaking them in salt water can help to improve their flavor. Cucumbers can be flavorfully enhanced in this manner without the use of additional ingredients or dressings. Cucumbers should only be submerged in salt water for a brief amount of time, typically no longer than 30 minutes, as doing so can cause them to become overly salty.
