Q.Green Butternut squash
My husband picked some large butternut squashes that are still green with stripes. Can I eat them? Will they taste any good? How should I cook them?
You can eat them, though they may not taste very good. However, sometimes you can ripen them off the vine. It just depends on how close to maturity they were. This article will help you try:
