Italian Castagnaccio Cake

Castagnaccio is traditional Italian cake made from chestnut flour, olive oil, nuts and dried fruit.
By Tamara Novakovic
I tried my first castagnaccio in Siena, Tuscany. It is their typical dessert, often eaten as a snack with a cup of espresso. This rustic cake is an acquired taste.  It is dense and rich, since the batter contains no raising agent, and subtly sweet. All the sweetness comes from dried fruit, generally raisins. There are variations where rosemary sprigs are also added to the batter.
Castagnaccio is best served with a cup of espresso or sweet wine like vin santo.
