Yes. In Australia, the cornmeal is labelled as Polenta. You can get it at Woolies or Coles.
Oh....is this a good time to mention that my daughter' name is Jemima? :D
Cornmeal is hard to find here. When I make cornbread, I use polenta, which is (I think) basically the same thing, and you should be able to get it at the supermarket easily.
WOW. I started reading this a couple of hours ago...what an adventure! My kids are now wondering why I haven't cooked them dinner! Luckily they forgave me when I showed them your photos. CONGRATULATIONS!!!!!
