Why does the Pearl in pearl milk tea harden when it is cold? What should I do in this situation? Can I soften it?
Soft and hard are related to its raw materials. When it is hot, it expands, and the gap between molecules is large, so it is soft. After cooling, the volume shrinks and the molecular gap shrinks, so it hardens.
