This cheesecake discussion raises several important questions related to
culinary history:

What is a cheesecake (or what is a definition of any dish)?

Are there essential ingredients/process that are necessary for a cheesecake (or
other dishes)?

Does this definition change over time?

When there is no clearly accepted source for defining cheesecake (or other
dishes), how much of our conversation is related to these linguistic matters?
