Several years ago, my husband and I had lunch at Gadsby's Tavern in Alexandria and I had this fantastic dish that I'm 99% sure was called "Turkey Cheshire." It was in a crock, had roast turkey, ham, and some sort of rarebit-like sauce, then baked. It was fantastic. The fine folks at Gadsby's were kind enough to look thru their recipe archives and came up with no such recipe. I'm stumped. My husband remembers it too. Recipe searches online have come up with nothing. Does anyone know about something like this? I've tried to emulate the dish and it always comes out so so.

A Hot Brown is usually made w/ bacon rather than ham, built on bread and not usually made in a crock, but yeah, what you had at Gadsby's basically sounds like a Hot Brown. They're pretty easy to make; the only real "cooking" part is the sauce, which is just a mornay (bechamel + cheese), so if you're trying at home and it's not wowing you, the sauce is probably what needs tweaking. (The original Hot Brown, created at the Brown Hotel in the 1920s in my hometown of Louisville, was reportedly just a rarebit + turkey; bacon has been part of the recipe for 70+ years now, though, and some folks also add pimentos, ham, and/or avocado.)
