Can you process squash that has been frozen outside?

Yes, you can process squash that has been frozen outside, but its quality may be compromised due to freezing temperatures. If the squash has not been frozen solid and is still safe to handle, you can cook or puree it after thawing. However, if it has been frozen for an extended period or shows signs of spoilage, it's best to discard it to avoid food safety risks. Always ensure that the squash is properly cooked before consumption.
