The document describes how kitchen technology and cooking methods have changed from the 1800s to 2007. In the 1800s, cooking was done manually using stoves, pots, pans and handheld tools. Electric ovens were simple without fans, and there were no electrical appliances like microwaves. Pressure cookers were used to cook food quickly on the stove. By the 1900s, enamel and aluminum pots were common cooking vessels. The document credits Alex T, Jayden J, and Mrs. Marlene Lewis for the information.
