Which element is not associated with the described NY style cheesecake?

The element that is not associated with New York style cheesecake is crumble crust. New York style cheesecake is traditionally known for its rich and dense texture, which is achieved primarily through the use of cream cheese and a standard graham cracker crust rather than a crumble crust. The graham cracker crust provides a firm and sweet base that complements the creamy filling.

In contrast, a crumble crust is often more crumbly and can be made from various ingredients including cookies or nuts, which is not typical for this specific style of cheesecake. The other elements—plain, strawberry topping, and whipped topping—are all commonly associated with New York style cheesecake. For example, it can be served plain or with various toppings like strawberry sauce or a dollop of whipped topping, enhancing the overall dessert experience without altering the foundational elements of the cheesecake itself.
