In another thread, someone describes a hamburger as a “Sandwich.”
I’ve noticed this before, and wonder if it’s a regionalism. I’ve never heard someone in real life call a hamburger a “sandwich.” A hamburger is a hamburger, or a burger. It is not a sandwich. To be, a sandwich is two peices of bread with stuff in the middle.
You even said it - bread with stuff in the middle. A burger is two pieces of bread with stuff in the middle. So is a hot dog. Kind of a specialty sandwich, but a sandwich, nonetheless.
Personally, a sandwich is bread with stuff in the middle. Everything else is known by their sub-group, although they are still technically “sandwiches.”
For me, the key to a sandwich is that it can theoretically be eaten while held in one hand and that there is bread protecting your hand from the filling. Bread with stuff in the middle sure. But hand held is also, I think, key.
Pita Pockets, Taco’s, Quesadilla’s, Hamburgers, Hotdogs and Ruben’s are all sandwiches. Open-Faced sandwiches, ironically, are not.
A sandwich can be hot or cold, but it requires a straight edge and corners - that is axiomatic to the theory of sandwiches. Where are the corners in a burger? Nowhere, my friend.
All of the above except “open-faced sandwiches,” which I consider a distinct category. I never refer to hamburgers as sandwiches myself, but definitionally I consider them to be part of that same group.
Open-faced sandwiches aren’t sandwiches, as the name implies. If you allow them to be classed as sandwiches then you get into sticky territory, would peanut butter on a slice of bread have to be classed as a sandwich as well, or jam on toast? Nah, not going to wash with this sarnie-lover! Two pieces of bread (or a piece of bread cut as in a hotdog) with something in between, hot or cold.
EDIT: I seem to recall in the film Good Will Hunting Casey Affleck refers to his burger as a sandwich. The film is set in Massachusetts and Matt Damon (one of the writers) was born there, so that might help with localising usage. shrug
All those are clearly sandwiches to me, with the possible/probable exception of open-faced sandwiches. (I grew up on all sorts of open-faced sandwiches–they were by far the preferred form in my house, so I really have no problem with lopping them in with sandwiches. But I can see the point against them.) By what definition is a hamburger not a type of sandwich?
Open face sandwiches aren’t true sandwiches because you can’t eat them bare-handed. Not without making a huge mess, anyway. (I’m thinking about things like sloppy joes and turkey ‘n’ gravy)
Anything between two pieces (or ON one piece) of bread is a sandwich. That is the parent name of that category of food. Then, it is further broken up by types of sandwiches. A tuna melt is an open-faced sandwich, a hamburger is a fast food sandwich and so on and so forth.
