Answer: Winter squash will taste watery and bland if not allowed to fully mature before harvesting. Wait until the vines die back and the shells are hard. A light frost can improve the flavor by changing some of their starch to sugar, but it will also shorten their storing quality. After the plants die down, harvest squash by cutting the fruit from the vine, leaving a 3-4 inch stem. Acorn squash can be stored in a cool, dry area, where they will keep for several months.
