Dear Corky and Lenny: Forgive me for straying. You know I've always loved your cheesecake, but sometimes . . . well, the flesh is weak, and I just couldn't help checking out the new joint in town. But honestly, once I tried it, it was such a letdown! Your cheesecake is sooo much better: Firm, not fluffy. Sweet, but not cloying. And so full of pure, cool dairy notes that adding whipped cream seems preposterous. So yes, your cheesecake is the best. From now on, no factory-made cheesecake will pass these lips again!
