The phrase references a tool, typically digital, that assists in determining the appropriate proportions of ingredients for revitalizing a sourdough culture. These ingredients usually include a portion of existing, mature culture, fresh flour, and water. For example, a common formulation might involve combining one part starter, one part flour, and one part water, often expressed as a 1:1:1 ratio. Such tools simplify the calculation process, ensuring accuracy when modifying feeding schedules or culture size.
Employing such a resource offers numerous advantages to the baker. Consistent ratios lead to a more predictable and stable culture, impacting the dough’s rise time and overall flavor. Accurate proportioning reduces the risk of culture imbalance, preventing unwanted sourness or inactivity. Historically, bakers relied on experience and intuition, but these modern aids provide a level of precision that minimizes error and promotes repeatable results. The application allows for scaling the recipe to fit diverse baking needs.
