The word 'Scone' appears to be the only fixed, immutable way of determining the position in the
class structure of a British person, depending on whether you rhyme the word with 'gone' or 'alone'. Although originally Scottish, the scone has been adopted as a slightly
posh treat throughout
England, and indeed scones are as much a symbol of Englishness as
cucumber sandwiches, cricket, and the
Maxim gun.
Scones are traditionally eaten with margarine and strawberry jam; contrary to the first write-up, they are not very puffy - rather, they are brittle and have a texture similar to cake, but drier.
Also, in Australia, 'scone' is slang for 'head', as in the common Australian phrase 'That gentleman over there - I do believe that he is off his scone' (meaning 'That fellow is insane - not clinically so, merely foolish').
