Query: Excellent covering many influenced regions around the world

This in an excellent cookbook that traces Indian influences around the world. It has loads of interesting and exotic recipes and also has many of the much loved standard dishes found Indian influenced areas around the world, including surprising places such as Kenya. The initial history of the Indian influences is fascinating. There are even recipes for creating 19th century "British" style curries and different curry powder recipes. It's a great cookbook for both someone getting into cooking this style of food or for someone already with lots of different cookbooks seeking something new and interesting.
