M.Ted, someone in Oz a few years ago did an academic piece on the fact that, since the 50s, the outside dunnies gradually moved inside and the cooking facilities gradually moved in the opposite direction. And it was also commented on that (stereotypically), while women ruled in the kitchen (males being happy to let them do so) males ruled the outside cooking; most outside cooking was of "meat" (none of this vegetable stuff), which also fitted into the stereotype.

And when I was in SC (US) I was introduced to the notion that populations could (and were, by academics) sorted into social, economic and geographic regions demographically, just by the sauce/s they did or didn't use when barbecuing. To an innocent from Oz the range of sauce possibilities was a real eye opener.

Cheers, Rowan
