A Wonderleaf question
Why does ice cream melt?
a real page from the book
Ice cream melts because warmth from the room moves into the colder scoop. That extra energy loosens the frozen water crystals that were holding it firm, so solid bits become liquid water. Once that icy framework gives way, the cream, sugar, and fat slump into a soft puddle.
The funny part is that not all scoops give up at the same speed. Airy ice cream can sag quickly, while denser gelato often keeps its shape longer. If a carton warms and freezes again, bigger crystals can form, which is why old ice cream turns grainy.
