What aspect does progressive cooking NOT primarily address?

Progressive cooking primarily focuses on techniques and strategies that enhance the efficiency and quality of food preparation in a commercial kitchen setting. This practice emphasizes aspects such as time management, which involves scheduling tasks to maximize productivity, and personnel efficiency, which entails optimizing staff roles and responsibilities for smoother operations. Additionally, the usage of available food is a key element, as it encourages utilizing ingredients effectively to minimize waste and maximize flavor.

Ingredient sourcing, however, is not a primary concern of progressive cooking. While it is important to choose high-quality ingredients for better end products, progressive cooking is more about the methodologies applied during the cooking process rather than the origins of those ingredients. Consequently, the aspect that progressive cooking does not primarily address would be the sourcing of ingredients, making this choice relevant in understanding the focus of progressive cooking practices.
