Using an 11" pan on a 9" element on an induction cooktop is generally not recommended. The size of the cookware should ideally match the size of the induction burner to ensure efficient and even heating. Here's why:
Uneven heating: When you use a larger pan on a smaller induction element, the outer edges of the pan might not receive sufficient heat, leading to uneven cooking. This can result in undercooked or overcooked food, as the heat distribution won't be optimal.
Energy efficiency: Using a pan larger than the induction element means a significant portion of the heat generated by the element will be wasted, as it won't be in direct contact with the pan's bottom. This can lead to higher energy consumption and longer cooking times.
Safety concerns: Placing a large pan on a smaller induction element can create stability issues. The pan might extend beyond the edges of the element, increasing the risk of accidental tipping or spillage.
Potential damage: Induction cooktops are designed to detect the presence of compatible cookware. If the pan's base doesn't fully cover the induction element, the cooktop might not recognize it as suitable cookware, and it may not function correctly. Additionally, the exposed edges of the induction element could be prone to damage if impacted by the larger pan.
To ensure optimal performance and safety, it's best to use cookware that matches the size of the induction element. For an 11" pan, you should ideally use it on an induction element that is at least 11" in diameter to ensure even heating and proper functioning of the cooktop. If you don't have a matching element, consider using a smaller pan or pot that fits the element properly.
