During my search for documents and letters relating to Martha Washington, I’ve stumbled upon numerous interesting articles. One of the most attention-grabbing pieces was a short recipe for “lettis tart.” To begin, I had to wonder – what exactly is “lettis”? I assumed it simply was “lettuce” misspelled, but when I googled “lettis” to confirm my hunch, I found a blog post about a modern attempt at the recipe. It identified “lettis” as iceberg lettuce. Though a little research suggests that iceberg didn’t exist in Martha’s time, the post was all I had to go on, and by this time curiosity had gotten the best of me, so I added the ingredients to my grocery list.
