Simplicity and a Starter is a sourdough-focused food and baking brand created by McKenna, a sourdough teacher and recipe developer. Its goal is to make sourdough baking simple, approachable, and enjoyable for home bakers, whether they are just starting out or refining their skills. The website offers recipes for both active sourdough starter and sourdough discard, covering breads, bagels, rolls, pizza, breakfasts, snacks, desserts, and savory meals.

Recipes range from long-fermented loaves to quicker options, helping bakers use their starter in a variety of ways and reduce discard waste. Visitors can also find practical guides on making and caring for a starter, understanding discard, troubleshooting proofing, and improving bread. Simplicity and a Starter provides a free email subscription featuring new recipes and baking tips, along with a free step-by-step starter guide.

For further learning, the brand offers a sourdough eBook and a collaborative cookbook. Its content is also shared through YouTube and social media, including Facebook, Pinterest, and Instagram
