A play on the word "doughnut." On the one hand, a doughnut is a sweet food that is often eaten with bitter coffee/teas for balance. But also, a doughnut looks like a life preserver, which is a flotation device that could be quite useful during a shipwreck, which is why the people in trouble are requesting it.
