Angel food cake help - is it cooked?

I bake a lot but just made my first angel food cake (made an ice cream cake for New Year's and had tons of egg whites).

It's been cooling for over an hour upside down now, and I just reached under to feel if it was still warm, and I touched what looks like some slime! I think the areas between the cracks are still wet!

I cooked this in my convection toaster oven, which cooks fast, so I put the timer for 5 min less than the recommended time. With 10 min left, I saw that the top had risen quite high and close to the top of the oven and was burning, so I stuck a piece of foil over it. When the timer rang, I pressed the top in a few spots, and the cake sprang back, so I figured it was done (didn't check for wet spots then) and inverted to cool.

Is my cake underdone? If so, what can I do? Or can I just chop off the wet spots? I'm assuming the wet spots include egg whites, and I don't want to get sick! Thoughts? Thanks! Happy New Year to everyone.
