Question

Is pie a countable noun or not?
Two sentences in a magzine:
She is going to make an apple pie (I think it's a countable noun here) for this holiday. Apple pie is ("is" is used here without "a" or "the" before Apple pie, I am confused) a very American dessert.

Answer

"She is going to make an apple pie" - one apple pie, for example. We're not being specific here.

"Apple pie is a very American dessert." -  here, we mean "apple pie" in the most general sense.  You simply don't use "the" when speaking in general.  As apple pie is a kind of food, we naturally follow the pattern for the uncountable noun "food".

Answer

Pie can be both countable and uncountable. It's uncountable when you think of it as a substance: "Apple pie is a very American dessert".
It's countable when you think of it as an object with well-defined boundaries and a well-defined shape ("she's going to make two apple pies").

Answer

Pies are countable.  Period.
