Offering the next best thing to a private baking and pastry class, Erin Jeanne McDowell teaches customizations for more flexibility: Buttermilk Biscuits can be cut in different shapes—Erin prefers squares, so there's no scrap dough left, and then add cheese (or fresh herbs or bacon) for bolder flavor. There are plenty of recipes here as well, including Jalapeño Waffles, Ultimate Garlic Bread, Smoked Salmon Breakfast Buns, Shepherd's Potpie, and even Green Eggs and Ham.
