You probably toast your average sandwich—and that works perfectly well, most of the time. But for a true melt, like this powerhouse tuna melt, consider the broiler.

As bread and other foods darken under the broiler, they absorb more infrared energy, which accelerates cooking. As soon as the color of your food turns, pay close attention to avoid overcooking. The broiler’s high heat breaks apart the emulsion of fat and protein in cheese, which helps send your cheddar or Swiss into a bubbly goodness.
