I've seen the term "slice" before - some fifteen years ago a friend sent me a stack of cookbooks from Australian Womens Weekly and one had the term "slice" in the title - I think. It has been some years since I came across them but as I never part with cookbooks (unless my arm is twisted) they are still around somewhere.
Occasionally I see other terms in baking and cooking and wondered if anyone had ever put together a "dictionary" of culinary terms unique to Australia.
I've seen a dictionary of slang terms (mostly geared toward sports) and surely cooking and baking is just as important to a significant portion of the population.
Here in the US, at least in certain areas, a "slice" refers exclusively to pizza.
There are some regional terms that are not understood by people in other parts of the US, not to mention foreign visitors.
One visitor from the UK, who had previously been in Nashville, TN, told me that he was totally confused by restaurant menus that had the listing "Meat & 3" followed by a list of various meats and alongside a very long list of vegetables and such.
He said he provided a great deal of amusement to the server and to other patrons as it was patiently explained that he could pick whatever meat he wanted and then choose 3 "sides" to accompany it. He said that he had never seen so much food on one plate in his entire life. This was accompanied by endless glasses of iced "sweet tea" - a particularly southern tradition, as well as a basket of cornbread or biscuits - no limit.
He swore that he gained 10 pounds during the 5 days he spent in Nashville. Then complained that he gained another 5 while staying with me.
I think that was because he discovered that he really liked authentic Mexican food in restaurants actually operated by Mexicans!
