CUSD Terms Explained
"Frame": The part of the sandwich you hold. e.g., bread, bun or wrap
"Essence": The filling. e.g., the cheese in a grilled cheese sandwich
A sandwich is an assembly of food parts capable of being held without great hardship or mess.
All sandwiches possess a frame that covers some part of the essence. The frame must be made of a material that is in an edible state when the essence is added, and must have an outlet that exposes the essence before the first bite is taken. In other words, the frame may not completely surround the essence (e.g., a burrito), though the essence need not actually be visible.
The essence of a sandwich can be any substance, as long as it is not formed into a non-natural shape (e.g., any burger). Note, however, that a substance formed into a non-natural shape that is sliced and assembled within a frame as described above qualifies as a sandwich (e.g., salami).
In coming days I will provide more examples about what is, and what is not, a sandwich. Feel free to suggest your own examples.
I welcome your comments and questions. The definition seems airtight, but I know there are those who would like to see it defeated. If exceptions are noted, this definition may need to be altered.
But I doubt it.
