Like so many great American sandwiches, this one sings because of its simplicity: thick slices of ham are the star, often accompanied by some lettuce, cheese, tomato and/or mustard. In fact, one of the best ham sandwiches you can make relies on the very first recipe for it to appear in the states, courtesy of cookbook author Eliza Leslie in 1840:
“Cut some thin slices of bread very neatly, having slightly buttered them; and, if you choose, spread on a very little mustard. Have ready some very thin slices of cold boiled ham, and lay one between two slices of bread. You may either roll them up, or lay them flat on the plates."
Simple — and simply perfect.
