We have these white squash...I think called scallop or patty pan. (We didn't plant them...just grew.) We used quite a few to make "mock apple pie & crisp" and they were excellent. I left some on the vine but still watering. I went oput and picked some yesterday and the outside is hard & thick. The previous ones I just peeled... very easy. I did find enough small ones to still make my pie but the others got tossed in the field. Did they cross w/ something else? Leave on the vine too long? Any ideas about this? Thanks!!!
