HEARTBAKE: Skip the hollow chocolate confections; cut out valentines from a sheet of Dufour Chocolate Classic Puff Pastry Dough instead. Made with unsweetened cocoa powder and a touch of confectioners’ sugar, it bakes up not too sweet. And it might be the best-smelling thing to emerge from your oven since the holidays. Bonus: It contains 1 fewer gram of fat per serving than the classic Dufour puff pastry. 14 ounces, $10.99. Available at some Whole Foods Markets and area Balducci’s stores.
