In a recent Italian language conversation meeting, talk turned to castagnaccio. Daniele, our born-and-bred Tuscan from Siena, recalled snacking on this cake. He remembered it in detail. It was made from ground chestnuts and olive oil embellished with raisins, rosemary, and pine nuts.
To my American ears, such an austere combination of ingredients didn’t sound much like any cake I knew. But since I had never sampled a castagnaccio, I decided to bake one.
I ordered chestnut flour on nuts.com and while waiting for it to arrive, I started researching recipes.
Pamela Sheldon Johns’ Cucina Povera seemed like a good starting point since this “cake” was clearly food of the poor. She shared a recipe but the head note gave me pause. “This dense cake is an acquired taste, and it has taken me almost twenty years to acquire it. But its musky chewiness is much loved by Tuscans.”
Patrizia Chen in Rosemary and Bitter Oranges was more encouraging. “Semisweet, tender, and distinctively nutty, castagnaccio is in itself worth a trip to Tuscany in fall or winter.” She also refers to the preparation as a pancake which seems a more accurate descriptor than cake.
