Fifteen degrees seems like a small margin to cause that many defects. Could there have been other factors with that batch, like the iron chemistry or the mold temperature?

Right? @henry38, it's wild how much time we waste on stuff that a simple text could fix.

Wasn't there a study about this?

Took a full cheesecake through security last year (don't ask why). The agent made me open the box, and everyone in line was staring. Ended up sharing slices with my row on the plane, and it was a huge hit. Now I always pack something shareable for long flights.

Understand that totally, my brother did the same thing!
