A Wonderleaf question
Why does ice cream melt?
a real page from the book
Ice cream melts because heat moves from the warmer room into the colder scoop. That energy loosens the frozen water crystals that hold the scoop firm, so solid ice changes to liquid water while the fat and sugar mix into a soft puddle.
The recipe matters too. Extra air can let a scoop cave in quickly, while a denser gelato may keep its shape longer. Repeated freezer-door openings make small surface melts refreeze into larger crystals, which is why forgotten ice cream can turn crunchy.
