Hot topic
Until my girls are old enough to contribute, at dinnertime my wife is the cook in the family and I am the dishwasher. She cooks in bulk to save effort as we can then eat leftovers a few times a week. As dishwasher, I have the honor of clearing the table and putting the leftovers in the fridge. Because we often have leftovers, we’ve invested in a couple dozen GladWare containers. So as I am putting sliced pears in a container, I read its lid: “CAUTION! CONTAINER MAY BE HOT.”
As far as I am aware, all grocers sell these containers empty and at room temperature. I believe the only way to warm them up is to put them in the microwave (ideally with food in them). This thermal law applies to non-GladWare containers as well, so the warning really belongs on the microwave: “CAUTION! PUTTING ITEMS IN THE MICROWAVE MAY CAUSE THEM TO GET HOT.”
But just in case I’m mistaken, I will start retrieving my GladWare from the cupboard with a pot holder.
