Awesome, another Brisbane Curry Forum member.
We nearly have enough to get together and have a bit of a curry day, I know of at least four in the Brisbane area who are on the forum.
The secret to Aussie Indian Restaurant Butter Chicken is in the gravy/paste that is used.
I know this as I work part time when I can in Indian Restaurants and also assist running the cooking classes with one of the chefs here in Brisbane. By day I'm a computer programmer.
It is very simple, no boiling of onions and no blending of them either, but easy & perfect Butter Chicken when the gravy is made right.
It's like most things unless you see someone do it, it doesn't make sense or turn out the right way. I notice that at the cooking classes too. For example one part of the process says ...turn the heat down low and cook the onions until they are dark brown and caramelized, do not let them burn!. Yet people rush through the process and start adding the ginger & garlic paste when the onions are no where near cooked.
Gotta run to drum lessons with the kids, will be back later with more...
