The ability to cook well, called "sazón" (lit. seasoning) is considered to be a gift generally gained from experience and a sense of commitment to the diners. For the Day of the Dead festival, foods such as tamales and mole are set out on altars and it is believed that the visiting dead relatives eat the essence of the food. If eaten afterwards by the living it is considered to be tasteless. In central Mexico, the main festival foods are mole, barbacoa, carnitas and mixiotes. They are often prepared to feed hundreds of guests, requiring groups of cooks. The cooking is part of the social custom meant to bind families and communities.
