A friend who volunteered making sandwiches for a soup kitchen was instructed to always spread both filling and butter or mayo over the entire slice of bread, crust to crust, to ensure the sandwich was not dry. Apparently not a universal rule.
We had a discussion elsewhere on the board sometime ago about the whole concept of buttering toast and bread to the very edges. I wish I could recall where it was because it was quite interesting. I believe the phrase was wall-to-wall!
