When I was producing
Off the Cuff for WFPL, I had the good fortune of interviewing David Hogan, author of
Selling 'em by the Sack, the entire history of White Castle, which goes back to the early 1920s. White Castle didn't invent the hamburger, but really helped legitimize it due to very strict sanitary requirements, quick service, and as good a coffee as you could get back in the day. And they were doing it long before Ray Kroc.
Rumors have always swirled around the chain - about what's in the meat (baby food is the most frequent ingredient you'll find in the clone recipes) and, more recently, that the onions aren't really onions anymore but rather onion flavored cabbage, which could explain some of the digestive, uh, interest.
I'm one of those weirdos who actually likes my cheeseburgers with tartar sauce rather than mustard, but I can't live without the pickle. That was Hogan's primary objection to the frozen variety, although it's pretty simple to keep a jar of hamburger dills in the fridge. The frozen ones are better if you thaw them first, of course, and sometimes it's difficult to wait. The times I most crave the darned things are the times I'm in the least suitable shape to drive to get them, though, so there's usually a box of six in my freezer, just in case
