I enjoyed the recipes I've tried from this book--this is real Indian cooking! But be prepared to spend a lot of money building up your spice collection. The first recipe I tried cost well over $50 to make. Obviously, once you have your spices, things won't cost so much.
Jaffrey always chooses authenticity over practicality. For example, in the recipe for Rogan Josh, she calls for 10 cardamom pods. These are very expensive, and since they can't be eaten, they must be discarded after cooking. Switching to cardamom seeds or ground cardamom saves money and hassle, and I noticed no difference in the taste.
Another frustration is the measurements. Jaffrey calls for potatoes and onions by the gram and ounce. How much is 225 g of potatoes? Why not just call for two medium russet potatoes?
Even though the recipes are fun to make and the results are delicious, I found this book unnecessarily frustrating and expensive to cook from.
