This phrase describes a specific type of bread-making process that utilizes the byproduct of sourdough starter maintenance within an automated bread baker. Instead of discarding the portion of sourdough starter removed during feeding, it is incorporated into a bread recipe designed for a bread machine. The formulation often includes ingredients like flour, water, salt, and sometimes yeast to create a loaf baked entirely within the appliance.
Employing this technique offers several advantages. It reduces food waste by repurposing the discard, minimizes resource expenditure by effectively utilizing a resource often thrown away. Furthermore, it imbues the resulting bread with a subtle tangy flavor characteristic of sourdough, while simplifying the baking procedure through automation. Historically, resourceful cooks have always sought ways to minimize waste, and this approach exemplifies that tradition within the context of modern bread-making.
