Just utter the words "La Broche" and you may find yourself embroiled in controversy. Controversy is La Broche's -- and its cutting-edge Spanish chef Angel Palacios's -- middle name. In fact debate has raged within these very pages about said avant-garde Spanish cuisine and its ingredients. But hey, creativity often stirs controversy, and this offshoot of the famous Madrid mothership is nothing if not creative. You definitely will want to try the Spaniard's signature "foam," used to top many a dish (raspberry foam on cauliflower soup, anyone?). But there's more to La Broche than foam. There are, for example, duck livers and rockfish, confits of lamb and codfish, sweet-potato cappuccino with ginger and coconut, turbot fillet with pork trotters. This is, for Miami, something very fresh and exciting. It is also expensive. But sometimes you have to pay for the best.
