Classic Tuna Melt
Some people say that the beloved diner and deli classic known as a tuna melt is a tuna sandwich topped with cheese and warmed on a griddle. Others say that it's clearly a grilled cheese sandwich with a tuna salad upgrade, especially since the legend holds that the first tuna melt was the result of a busy fry cook in Charleston, South Carolina, spilling tuna salad onto a grilled cheese sandwich. Either way, it's a retro combination that we've always loved, one that's soared back into popularity in recent months as we look for tasty, satisfying, warm meals that we can make with items on-hand in the pantry and fridge.
The signature elements of any Tuna Melt are bread, cheese, and tuna salad.
Although there are fans of open-face tuna melts on English muffins, most devotees insist on it being a closed sandwich assembled between two slices of sturdy sandwich bread and griddled until the cheese melts and the bread crisps. Most people butter the bread out of habit, but others insist that the key to perfect pan-toasting or griddling is to spread the outside of the bread with mayonnaise. Butter adds flavor, but mayo creates a picture-perfect, golden-brown finish on the bread, ensuring that every bite will crunch.
Next comes your go-to cheese for grilled cheese, which can be sliced or shredded.
The perfect tuna salad is in the eye of the beholder, but for a tuna melt, it should be moist enough to bond with the bread and melting cheese, but yet not so goopy that it spills out. Recipes used to state the amount of tuna in the number of cans, but over the years the sizes and contents of the cans have changed so much that it's no longer a reliable measurement, not to mention the advent of tuna in pouches. However you buy your tuna (water-packed, oil-packed, or dry-packed), open enough containers to yield 1 cup of drained, flaked tuna for this recipe.
