Thank you Dalpuri, very enterprising. Who would be an author these days!
Livo thank you for your efforts in compiling those links. I can see that in having varied base sauces, some of which are used in differing proportions to make different dishes it's similar to the Aussie recipes, however looking at the recipes that Frank has posted they don't seem all that close to the long-fried onions which form the basis of the sauce recipes Masala Mark posted. Similar idea perhaps but with quite a different execution.
