"So, you, home cooks, even you home cooks with access only to a Safeway or Kroger, a 5-by-4-foot kitchen in a fifth floor walk up and an hour’s spare time between work, sleep, errands, kids, laundry and bill paying: Buy a duck breast and pack it in kosher salt and refrigerate it for a day and then rinse it off and enfold it in cheesecloth (or anything that can breath, a clean handkerchief will do in a pinch) and let it dry for a week on a rack on the counter or dangling from a string—then, slice it and taste. Suddenly you will see. Buy a side of salmon—no, buy a piece of salmon—pack it in an equal mixture of salt and sugar and some citrus zest or fennel, wrap it in foil for 24 hours, rinse it and taste a paper thin slice. A cooking miracle."
