This a serious debate that needs to happen.

I don't understand people who keep ketchup in the fridge its too cold! Ketchup should be at room temperature so it doesn't cool down your hot food too much but cools it down just enough to make it enjoyable.

Pack says to keep it in the fridge once open.

I don't think so.

For the record, the answer is "fridge".
