I like my chocolate tarts like I like my men: sophisticated, rich, deep and dark. The next time you need a dessert for a grown-up party, reach for David Leibowitz's super-easy yet drop-dead gorgeous Chocolate Tart . It's not for children. It's rich, but not overpoweringly so. I've made it three times now. It's very easy, and not very fiddly at all. The scariest part is making the caramel, and even that gets easy once you do it a few times. And once you make the easiest French pastry crust ever , you will wonder how you lived your life without it.
