Back in 2001, when we were working on our cookbook, farro was still rare. If you went to the right restaurants, if you frequented the vortices of culinary hipness. Italian delis, in New York or San Francisco maybe. Specialty food stores, the occasional sighting. How the world has turned in a dozen years! Now you can often buy farro in grocery stores, which is a good thing if you want to make this week’s Tomato – Farro Soup.
