Cucumbers are 96% water. They age faster when stored for any length of time with tomatoes, melons or apples, and at temperatures over 50 degrees. The cucumber’s smooth skin keeps the water in like a jug. Their flavour is in their seeds.
Medium sized cucumbers with soft small seeds have better flavour. Botanically cucumbers are classed as fruit. They are one of the oldest vegetables, cultivated for thousands of years in India and parts of Asia. Some people believed that cucumbers were poisonous and they used to scrape their skin with a fork to let the poisons out! Of course, cucumbers are not poisonous.
