What's the best way to store strawberries? For strawberries to stay fresh, do not wash them right away. Refrigerate them as soon as possible in the original flat or in a container with a dry paper towel at the bottom. Separate the berries by layering them with paper towels to maximize freshness. Just before using, wash strawberries with the caps attached under a gentle spray of cool water. For best flavor, serve strawberries at room temperature.
