What is the main difference between over easy and over medium eggs?

The main difference between over easy and over medium eggs lies in the firmness of the yolk after cooking. When eggs are cooked over easy, they are flipped and cooked just long enough to set the whites while keeping the yolk runny and soft. In contrast, over medium eggs are cooked longer, resulting in a yolk that is partially set but still has a creamy texture. This distinction in firmness allows for different preferences in yolk consistency when served.

The options related to yolk color, cooking time, and type of skillet used do not accurately represent the key difference in texture and doneness between over easy and over medium eggs. While cooking time does play a role, the primary characteristic that defines over easy versus over medium is indeed the firmness of the yolk.
