ELI5: What causes the “refrigerated taste” food can get when it is uncovered in the freezer too long?
gpt
All the food inside is drying out and all the moisture takes smells into the air with it. The fridge is closed and small, so all that smelly air is trapped in there. Over time, food left in there a long time will have a dry crust and the humid smelly air will start to go back into the dry crust. The yucky taste and texture is all those mixed smells and dried out crust combined.
