I have this book
It is NOT restaurant recipes at all
They are homestyle versions of restaurant meals
For example
Chicken Tikka Masala is made by marinading the chicken, then boiling the whole lot!
Vindaloo has cardamons, cinammon,cloves,mace,cumin,chili,vinegar and potatoes in it.
It's a waste of money for us lot
No curry gravy in the recipes (except one)
I actually bought my copy from America
