Halloween is a popular “chestnut party” in many parts of Spain. As Castañada, it has Celtic roots that go way back and is closely related to the cult of the dead. The culinary star of the "deadly" feast is, as the name would say in no uncertain terms, the castañas or chestnuts. But due to drought and prolonged warm weather, chances are that there won’t be an abundance of the nuts. Just the same, leave it to the Spaniards to keep up their marvelous traditions, dead or alive.
