Editor’s Note: In April 2017, our colleague Caitlin PenzeyMoog wrote “Salt grinders are bullshit, and other lessons from growing up in the spice trade” for our sister site, The A.V. Club. That story yielded a book deal, and two years later, that book has arrived. On Spice: Advice, Wisdom, And History With A Grain Of Saltiness will be out January 15 from Skyhorse Press. This is an excerpt from the book.
