I’ve been thinking of placing a shallow steam pan (filled with cooked food) inside a deeper steam pan (filled with hot/boiling water) to keep food warm longer. This might come in handy for parties where food sits around. The pans would not be connected to any heating element. So when the water in the pan cools down, I would simply replace it with more boiling water.
I’ve been wondering about how deep of a pan I should use for holding the hot water.
So my question is: Will a deeper pan filled with more hot water stay warm longer than a less deep pan? In other words, does the volume of hot water matter?
