Simple, light, and easy to digest – the modern Hildegard cuisine for health-conscious individuals. "Simple Cooking" offers a contemporary, light kitchen based on local products and aligned with the principles of Hildegard's teachings. The approximately 200 recipes are tailored to today's needs: easy to prepare, clear ingredient lists, regional ingredients, straightforward and clear recipes, practical storage, convenient ring binding, and appealing photos. This successful book, which has sold over 40,000 copies, was followed in 2011 by "Hildegard of Bingen - Simple Cooking 2: 250 New Healthy Recipes.".
