Can I substitute chestnut flour with another type of flour?

How long does Castagnaccio cake stay fresh?

Castagnaccio cake is best consumed within a day or two of baking. However, you can store it in an airtight container at room temperature for up to three days. The texture may become denser over time, but it will still retain its delicious flavor.

Can I add other ingredients to personalize my Castagnaccio cake?

Absolutely! While the traditional recipe calls for specific ingredients, you can get creative and add your own twists to the cake. Consider incorporating flavors like orange zest, chopped nuts, or even a touch of rum or almond extract to customize the taste according to your preferences.

Is Castagnaccio cake suitable for people with dietary restrictions?

Can I use dried chestnuts instead of chestnut flour?

While it is possible to use dried chestnuts to make your own chestnut flour, it requires additional preparation and processing.
