Sarah Owens spent years baking conventional baked goods, only to slowly realize she had developed a crippling inability to digest or tolerate their ingredients. Unable to enjoy many of her most favorite foods, she knew she must find a health-sustaining alternative. Thus Sarah started experimenting with sourdough leavening, which almost immediately began to heal her gut and inspire her anew in the kitchen. Soon after, her artisan small-batch bakery, BK17, was launched, and with that, a new way to savor and share nutritious sourdough breads and treats with her Brooklyn community. In Sourdough, Sarah demystifies keeping a sourdough culture, which is an extended fermentation process that allows for maximum flavor and easy digestion, showing us just how simple it can be to create a healthy starter from scratch. Moreover, Sarah uses home-grown sourdough starter in dozens of baked goods, including cookies, cakes, scones, flatbreads, tarts, and more--well beyond bread. Sarah is a botanist and gardener as well as a baker--her original recipes are accented with brief natural history notes of the highlighted plants and ingredients used therein. Anecdotes from the garden will delight naturalists and baked-goods lovers among us. Laced with botanical and cultural notes on grains, fruits and vegetables, herbs, and even weeds, Sourdough Baking celebrates seasonal abundance alongside the timeless craft of artisan baking.
