Curry: A tale of cooks & conquerors by Lizzie Collingham is my current quest to further culinary knowledge. I’ve read a fourth of the book and learned more history then I was taught in high school about other countries. But I grew up in the West, in America, and here it is about cowboys and cows, not curries, vegetables, and Persian overlords.
This is not a recipe book, it is one person’s view of how curries evolved in India through the influence of other cultures. And it is an academic, not popular, view.
