How come people say not to put hot food in the fridge?

That’s an interesting question! I think it’s mostly a convention, and then maybe also practical. I can tell you the “conventional” reason, and I could tell you what would happen if you put it in, but I can’t tell you if this is actually the best option for you.

Well, what are the reasons?

When food is hot, its moisture is released in the form of steam. The warm water is rising inside the container, so the liquid is more dense than the air, and so if you seal the container there will be some pressure inside it, like a party balloon. If you put the container inside the refrigerator, the air inside the fridge is chilled and so it is more dense than the steam inside the container. If you let the pressure build up too much, the food will rupture the container and spill everywhere.

That makes sense. Are there other reasons?
