QUOTE : You will encounter a fifth taste.<br />Umami: uni, or sea urchin, anchovies, Parmesan, dry-aged beef with a casing of mold. It's glutamate. Nothing is a mystery anymore. They make MSG to mimic it. It's the taste of ripeness that's about to ferment. Initially, it serves as a warning. But after a familiarity develops, after you learn its name, that precipice of rot becomes the only flavor worth pursuing, the only line worth testing.
