'As a Brit (from Yorkshire, specifically) the word "Pie" evokes thoughts of savoury dishes like pork pies, chicken pie, etc.'
I believe that in USA "pie" is another word for pizza. Though they also have apple pie. In Australia, we agree with the Brits, especially the good old Aussie meat pie, AKA mystery fun bag. We also have apple pies and fruit pies. Six of one, half a dozen of the other, would feed a family.
