In a professional cooking context, what does a chef need to ensure while making a béchamel sauce?

In the context of making a béchamel sauce, the choice to avoid metal utensils with certain pans is significant due to the chemistry involved in cooking. When utilizing non-stick or delicate pans, metal utensils can scratch the surface and potentially release harmful chemicals or create issues with the pan's cooking performance. Therefore, choosing the right utensil that complements the pan is essential for maintaining the integrity of both the tool and the cooking surface.

Furthermore, while stirring continuously to avoid sticking is crucial for a successful béchamel sauce, as is cooking at a moderate temperature, the connection between utensil choice and the quality of the sauce and the cookware makes option C particularly relevant. It emphasizes the importance of using appropriate tools that prevent damaging your kitchen equipment, thereby ensuring a better cooking experience and end product.
