Modular Roaster: Wear-Ever Aluminum Multi-Part Roasting Pan System,

Produced by the Aluminum Cooking Utensil Co. (T.A.C.U. Co.) in the USA, this was a high-end, versatile kitchen tool designed to be used in several configurations.

• Standard Roasting: The deep bottom pan acts as your primary roaster for meats or casseroles.

• Steaming/Draining: The perforated insert  fits inside the pan to lift food away from fats or to steam vegetables and fish.

• Tiered Cooking / Extension: The open-bottom "ring" or collar acts as an extension to the height of the pan, allowing you to roast larger items (like a turkey) or to stack another pan on top for multi-level cooking.

• Self-Basting: When the shallow pan is flipped and used as a lid, the indentations help moisture condense and drip back down onto the food.

• Patent Number: The number 1788817  refers to a patent granted in 1931 for a "Cooking Utensil" handle and lid design, confirming this set's "Art Deco" era origins.

• Material: It is made of thick, "hard-wrought" aluminum, which was prized at the time for its superior heat conductivity compared to steel.
