Here is where the lines really blur. A hamburger’s soul is a ground meat patty, typically beef, formed, seasoned, and cooked directly on a grill or griddle. This isn’t a slice of deli meat; it’s a sculpted, seared entity.
A sandwich can feature any protein—sliced turkey, roasted chicken, tuna salad, or even leftover meatloaf. The construction is about layering slices or spreads, not shaping a primary element. That single distinction changes everything about taste and texture.
Fun fact: The first hamburger patty was reportedly served between two slices of bread at a 1904 World’s Fair. It was a sandwich then, but its patty-centered destiny was already clear.
