I've gotten into the habit of listening to audiobooks before I fall asleep, which means that I miss a great deal of the content of the books.
My recent audiobook was Extra Virginity: The Sublime and Scandalous World of Olive Oil by Tom Mueller. I was amazed by the history and processes involved with this historic food. I had no idea what cold pressed meant or any of the other intricacies of manufacture. I recommend the book.
I'm very excited to try the Olio Nuovo currently at Costco because it's going to be wonderful. From the book, I learned this is valuable and rare. Although, because I slept through a great deal of the book, I'm not sure exactly why.
