Emblematic? No. *some audience laughter*
Pre 1500? No.

A summary: This is ABSTRACT and MINERAL/VEGETABLE, with ANIMAL and VEGETABLE connections. The answer is three words, including a definite article, and begins with P immediately followed by a vowel. The abstract and mineral/vegetable are different descriptions of the same thing. The mineral/vegetable description is in part plastic (I think) and is manufactured. The abstract meaning is not figurative. The animal connection refers to one particular non-human species, and is not emblematic. The vegetable connection is connected to food but neither it, nor the overall answer, is a dish.

The answer is primarily or perhaps exclusively associated with the UK and dates from sometime after 1500. It is not art (except under a very broad definition), nor a method of cooking. It is not environmental, nor is it game-related.

Three questions provoked odd reactions from the audience, viz: "Passing the buck?", "Is it game-related?", and "Is the abstract meaning figurative? (E.g. the cat's whiskers)". The suggestions that it was art and that it was emblematic also provoked amusement.

Pink Panther? No *considerable audience applause, nonetheless*

Going from the particular to the general.

Fictional beast? Yes. *applause*
