I am halfway through McIlhenny's Gold: How a Louisiana Family Built the Tabasco Empire. It's well-written and the geological facts about Avery Island (one of largest salt domes on earth), as well as how the family was able to trademark the word "tabasco" (illegally through political connections) are quite interesting.
When we were moving from the east to AZ in 2003, we stayed in New Iberia but didn't take the time to tour Avery Island and I always regretted that decision.
