when does a grilled cheese become a melt
Melt sandwich One common filling is tuna with mayonnaise; the result is a tuna melt sandwich. Other popular choices are ham, roast beef, chicken, turkey, or a hamburger patty, which is known as a patty melt. It is the filling that establishes the melt sandwich as a variation of the grilled cheese sandwich. Patty melts were a staple of the traditional U.S. diner and were commonly found on menus as far back as the 1950s and possibly the 1940s.
Colby cheese Colby is similar to Cheddar, but does not undergo the cheddaring process.[3] Considered a semi-hard cheese, Colby is softer, moister, and milder than cheddar because it is produced through a washed-curd process.[4] During this process, the whey is replaced with water during the cooking time, reducing the curd's acidity, and resulting in Colby's characteristically mild flavor. As with most other cheeses, it takes a little more than a U.S. gallon of milk to produce one pound (just over 8 liters for a kilogram) of cheese. Monterey Jack cheese is produced almost identically to Colby, but Colby is seasoned with annatto which gives it a sweet nutty flavor and its orange color.[3]
