The practice involves utilizing the portion of sourdough starter removed during feeding, often called “discard,” to create a pizza crust baked in a cast iron pan. This culinary technique leverages the unique properties of both the discarded starter and the cooking vessel to produce a distinctive pizza. For example, a baker might use 100 grams of sourdough discard, combined with flour, water, and salt, to form a dough that is then pressed into a preheated cast iron skillet before topping and baking.
Employing this method offers several advantages. It reduces food waste by repurposing the discard. The fermentation process in the sourdough contributes to flavor complexity and digestibility. The cast iron pan ensures even heat distribution, yielding a crispy bottom crust and well-cooked toppings. Historically, resourceful cooks have long sought ways to minimize waste and maximize flavor, making this approach a continuation of time-honored kitchen traditions.
