ELI5: Why should you not defrost things, then refreeze them?
gpt
A couple reasons. One is bacterial build up. Another is texture. When you freeze something in a normal freezer, ice crystals build up and damage the cells. When you thaw it, those cells rupture. This leads to a bad texture and makes it more available for bacteria. Freezing again just causes more damage.
