I've got the eBook but one thing puzzles me.
In the videos he marinates his chicken and lamb in a yogurt mixture overnight and cooks the next day.
In the eBook he just cooks them from "raw" with no yogurt marinade. There's no mention of marinating that I can find anywhere in the book.
Is this maybe a future addition or did he reckon the marinating step would be a bit OTT for beginners reading the book?
I'll continue to use the yogurt method myself.
However some great new information, like how to make that garlic ginger paste, seasoned oil etc. And a massive explanation of the importance of onions in BIR

One other question for any Antipodeans on the forum, I can't get that curry powder he mentions to go into the dry mix and have been using the Aussie Clive of India. Anyone know of a good pre prepared curry powder available over here? We also have Keens Curry Powder but that's a bit "School dinner or Army Barracks style curry" if you know what I mean and is very heavy in fenugreek as a major ingredient.
