The person who coined the phrase "cool as a cucumber" may have had other intentions, but the phrase is based on fact. According to Food Reference, the inside of a cucumber is up to 20 degrees cooler than the outer peel. Fresh from the garden on a hot summer day, cucumbers provide a crisp refreshing snack. When stored properly, they maintain their texture and flavor for up to a week after being picked.
Harvest cucumbers early in the morning before the heat of the day has warmed them. Moisture content is highest in the morning when the flesh is crisp.
Wash cucumbers in cold water to remove soil or garden residue. Dry with a soft cloth.
Store in an area with temperatures between 45 and 55 degrees. Maintain relative humidity of 85 to 95 percent.
Refrigerate cucumbers in your home refrigerator for up to seven days to maintain freshness and flavor. Although the refrigerator is typically colder and less humid that optimal conditions, it is often the best choice for home gardeners.
Prepare and serve cucumbers immediately after removing from the refrigerator.
