Andrea's busy baking her favorite no-knead bread with a new-to-her (but almost 100-year-old) international sourdough starter. In honor of National Apple Month, Stefin revisits the Apple Pie Breakfast Cookies introduced in Episode 45. Pumpkin Cake Donuts are a fall favorite, but who can solve the mystery of the disappearing cinnamon sugar? It's also National Cookbook Month, and the duo introduce new recipes to challenge themselves: Victoria Sponge for Stefin, and Valencia Orange Cake for Andrea. Andrea (literally) sings the praises of her key ingredient, distracting Stefin from the most challenging aspect of her cake: The fact that there are no measurements! Finally, Andrea has a review of Ottolenghi's new book, Sweet, and Stefin runs down a list of Preheated listeners' most-loved cookbooks.
