Nice tutorial Red,I also have this book, it's very good although I tend to use variations from one called "you can cook Indian takeaway" because I was trying to avoid all of the ghee, I mainly buy the spices whole, toast them and then grind as per Red's tutorial, if you really want to cheat use those spice jars patak's (sp??) not the stir-in sauce jars obviously, I even saw Jamie Oliver use them in one of his shows....
I really don't like cardamom or cinnamon, and leaving them out does distract form the original or expected taste, unfortunately if you want the real thing you really have to go with the ghee, salt, sugar and all the other bad things, there is also a trick to cooking the onions for a little longer to break down the sugars I believe and that really brings out the taste, this is not burning them BTW, I will try and find the reference to it in my books
These are really worth a try, very rewarding to make yourself and a taste of home when you are a few thousand miles away from the local tandoori
Also I never found anything in India that compares to our proper Indian food (in the UK) and they just call it "food" anyway
