TL;DR
A Mad Tasting food guide describes castagnaccio as a dense Tuscan cake made mainly from chestnut flour, water and olive oil, often topped with dried fruit, pine nuts and rosemary. The source offers a basic recipe and presents the cake as a rustic use of regional ingredients; it provides no new reporting, named sources or evidence of a recent rise in popularity.
In its recipe, Mad Tasting says to mix 2 cups of chestnut flour with 1½ cups of water until smooth, then add 2 tablespoons of olive oil, a pinch of salt and a handful of raisins or currants. The guide describes the batter as thick but pourable and recommends spreading it evenly in a greased baking dish.
Mad Tasting’s instructions call for a topping of pine nuts and chopped rosemary before baking. The supplied excerpt ends before giving the baking temperature, duration or later steps, so those details cannot be confirmed from the material provided. The guide also suggests chopped chestnuts or walnuts as optional additions and notes that recipes vary.

From local staple to home recipe
A Cake Shaped by Chestnut Country
Mad Tasting links castagnaccio to areas where chestnuts were a familiar rural food and describes the cake as a way to turn a short list of locally available ingredients into a filling dish. The guide offers readers a practical point of entry to a regional food tradition, but it does not document a specific historical period or provide independent historical evidence.
For home cooks, the guide points to the compact ingredient list and chestnut-forward flavor as features of the recipe. Mad Tasting calls the cake suitable for people seeking a gluten-free treat, but it does not identify a particular flour product or address cross-contamination, so that label depends on the ingredients and preparation used.
