Hm -I'm quite pedantic, but not officiously so. I don't think the Cheese and Grits passes for a soufflé, although it might get a nod as a "soufflé" in an informal environment. I think the point made about technique is extremely valid. If you call it a braise, ain't no way, no how you can pass off a roast as a variation of the dish. When you tie a dish to a specific culinary technique, you have a lot less wriggle room than say adding a little cream to a carbonara. In fact, now that I think about it, technique is key (if you reference your dish in this way), ingredients less so.
