Which ingredient is NOT typically included in the classic version of Eggs Benedict?

The classic version of Eggs Benedict traditionally consists of poached eggs, English muffins, ham (or Canadian bacon), and a rich Hollandaise sauce. Each of the other ingredients plays a fundamental role in creating the dish. The poached eggs provide a creamy texture, the English muffin serves as a base, the ham adds savory flavor, and the Hollandaise sauce ties everything together with a buttery and tangy note.

Avocado, while it may be a popular addition or alternative in modern variations of Eggs Benedict—often referred to as "California Eggs Benedict"—is not part of the original recipe. This variation typically seeks to cater to dietary preferences or trends rather than adhering to the traditional ingredients that classify classic Eggs Benedict. Thus, the omission of avocado confirms that it does not belong in the classic preparation.
