Pecan pie may be the most satisfying, deeply pleasurable dessert known to humankind. It's simplicity itself: nothing but pie crust filled with corn syrup, butter, and nutmeats. Too often, though, the crust is dry, the syrup is gummy, and the pecans are chewy, burnt, or practically nonexistent. Farmerbrown, a stylish nouveau soul restaurant in the Tenderloin, crafts a triumphant pecan pie with a flaky crust, a luscious filling, and an abundance of rich, buttery, crunchy pecans. The flavor is candylike without being too sweet, the texture is moist and succulent, and there's a warming hint of bourbon in the filling. The house mint julep makes a fine accompaniment.
