Which of the following is NOT considered an approved smallware for blackening fillets?

The correct answer is that a 1/6 clear pan is not considered an approved smallware for blackening fillets. Blackening is a cooking technique that requires high heat and is typically done in a skillet that can withstand these temperatures, allowing for the proper searing and flavor development of the fillets.

A 1/6 clear pan is designed for storage or serving and does not have the heat retention and distribution properties necessary for effective blackening. It is too shallow and not suitable for the intense heat involved in this cooking method. In contrast, both non-stick skillets, cast iron pans, and 304 stainless steel pans are designed for high-heat cooking and can achieve the necessary sear and flavor profile that blackening requires.
