Nothing but the mustard.

nothing beats good ham and swiss for me... maybe a bit of good mustard as a finishing touch... a nice grainy or Dijon is always fine, but I might be in the mood for a honey mustard or as a Cape Codder, I'm also partial to Cranberry Mustard.

mustard, cheap white bread and swiss cheese

smoked ham, obviously, and generous amounts of mustard, Gruyère, and fresh ground black pepper, then pressed between two hot griddles. Although I recently tried replacing the Gruyère with some Wisconsin Brick cheese. The result was delicous. A few thin slices of apple is never a bad thing either.

honey mustard and american cheese on pumpernickel

With an applewood-smoked ham, I might be tempted to make a marmalade of apples and onions, roasted separately, then chopped, cooked briefly in reduced cider with a little sage, then cooled. Whole-grain mustard, too. Crusty thick slices of slightly tangy bread. Wedge of rosti on the side.

With a salty country ham from Viriginia, on the other hand, I'd take a long-cooked mess of greens. Chop. Sauté in some of the pot likker to dry out a bit. Cool to room temperature. Kaiser rolls with the same kind of mustard as above. Warm potato salad or sweet potato fries at this time of year. Summer? Coleslaw and cold picnic-style potato salad with the works.

horseradish, Guggisberg baby swiss and some hearty, whole grain bread. YUM!

My recent favorite ham sandwich is fresh ham, swiss cheese, lettuce, roasted pepper, and whole-grain mustard, on a crusty olive roll. I'm trying to figure out a good way to involve horseradish in it, though, since I've been reminiscing about a canape I used to make that placed a mixture of sour cream, horseradish, and grated Granny Smiths in a Westphalian ham cone. Mmmmmmm. Why serve 'em to company? Eat 'em all myself!

The ham sandwich from the Gotham Bar & Grill Cookbook.

watercress!

Ham, Gouda, Honey Mustard on good white bread!

Oh, good smoked ham with a slice of cheddar on "pan de agua"--a crusty bread sold at the bakery in the plaza near the beach my family goes to (and I used to go to when I was a kid) in Puerto Rico. There was always a little crunch from the grains of sand that got flung into the sandwich, no matter how hard my mom tried.

Of course, I love a good Cuban any day and you can't just use any old crappy ham--the good thick stuff is best.
