Raghavan Iyer looms large in Minnesota's culinary landscape. Over the years he's introduced us to the warm and wonderful flavors of India through his cookbooks, spice blends, cooking classes and restaurants.
His latest book, "On the Curry Trail: Chasing the Flavor That Seduced the World," traces the complex history of India's spices and their effect on world cuisines.
It will be his last book. After landing the contract, Iyer was diagnosed with Stage 4 colorectal cancer. He has been living with the disease for five years, longer than most, but as the cancer has spread to his brain and lungs, Iyer has publicly acknowledged that this will be his final chapter.

"This book is not an homage to my death," he recently told the New York Times. "This is really celebrating life, family, friends and food."
An innate teacher and animated host, Iyer approaches the book with warmth and expertise as he invites cooks to build their own spice mixture — toasting and grinding whole spices for what he calls the Mother Blend — before plunging into the fascinating history of curry as it crisscrosses the globe.
"I wanted to do a companion story to the '660 Curries,' " Iyer said in a recent interview about his 2008 groundbreaking cookbook. "I thought what better way to look at curries than through the lens of the Indian diaspora? It was propelled primarily through colonialism, with Indians as indentured servants and slaves."
"On the Curry Trail" includes a breathtaking amount of research on both world history and the Indians who resettled throughout the world, whether by force or choice. Much of that research was done by former Minnesota Public Radio archivist Margaret Bresnahan, who Iyer said did "a brilliant job" of capturing and distilling 6,000 years of trading history.
"It's such rich information," he said. "It really was quite important to have that. I could sift through it and start answering some of my own questions."
