Final answer:
The colonel's recipe for fried chicken became Kentucky Fried Chicken's signature dish since the Great Depression, marking a significant shift in food history that coincides with changes from the Industrial Revolution like the advent of fast food with fish and chips in England.
Step-by-step explanation:
The colonel's recipe for fried chicken is Kentucky Fried Chicken's signature dish and has been since the Great Depression when he first started as a roadside business. This speaks to the broader historical context of how food and consumption patterns have changed over time, particularly with the advent of the Industrial Revolution. Similar to how fish and chips became the world's first greasy, cheap, and wildly popular fast food in England, the colonel's fried chicken became a staple in American fast food culture. It's an emblematic example of how certain foods can be transformed into cultural icons over time.
