What are these spots on my butternut squash? I just roasted a bunch of butternut squash for dinner and am getting to puree, but am noticing that some of the pieces have weird glue-looking spots.  It sort of looks like when water weeps out of the pores on the squash, only it's white and the consistency of silly putty.  They're very small spots (like the size of a straight pin head), and close to the skin on the flesh, on the cross-section.  I feel like I'm describing this poorly. Here's a picture:



My question: Is this stuff safe to eat, or do I need to compost it and find something else for dinner?  I'd rather not give my whole family food poisoning!
I have seen those before when I have cooked squash; they seem more common when I microwave it. I suspect they are just starchy deposits. I have always just wiped them off and eaten it anyway.
