Its not a but plug. Its an urn.

Though it might be considered pizza, when people "make food" it is assumed that it is in its final finished form. You dont make eggs and then they are raw. The same you dont make pizza and its raw. (See how i talked about eggs too lol). In the context of the question pizza would take longer to be made cold.

I like to argue on the internet too. I find it really fun sometimes.
