Now, back to the task at hand - determining if your butternut squash has gone bad. The smell test is a great place to start: if it smells Sour or fermented, it's likely bad. Take a closer look, and if you notice any mold or mildew on the surface, it's time to toss it.
Another way to check is by looking for slime or sap on the skin - if it's sticky or oozing, it's a sign that the squash is breaking down. And, let's not forget about the color: if it's developed brown or black spots, it's probably past its prime. Don't worry, it's not the end of the world - you can always just grab a new one!
But what about the stems? If the stem is dry and brittle, it's a good sign that the squash is fresh. On the other hand, if the stem is soft and soggy, it's likely gone bad. It's all about the little details, my friend!
