A great many sandwiches start as other meals, but very few of them start as soup. It takes a special sort of thinker to turn soup into something hand-held, and it takes an especially talented sort to do it well. Thankfully, Clementine possesses just that sort of person. Gruyere and caramelized onions join braised beef brisket on wheat levain, pressed to warm melted delight and served with a cup of jus. It’s richness upon richness, which is an incredibly difficult thing to do successfully. Contrary to what you might expect, this isn’t essentially without harmony. Everything works in the same direction, and so it isn’t that one side can drown out the other as they both combine for a loud, deliberate note. That’s what you find here, just umami on top of savory, deeply rich and just outstanding. Maybe one of the 10 best sandwiches I’ve ever had, and if you’re anywhere near Los Angeles I cannot recommend it enough.
