Today is the Feast of All Souls in the Catholic Church, and the Day of the Dead (Día de los Muertos) in Mexico, an occasion which seamlessly blends Christian beliefs with rituals so ancient the Aztecs would probably recognize them.
Families reunite to tend their ancestors' graves and honour them with offerings including flowers, food and little sugar skulls, in place of the real ones the Aztecs might have donated, and, of course, drink. Ancestors seem to favour bottles of pulque, tequila, mezcal or the porridgey corn drink known as atole. Get in the spirit by mixing up an Oaxaca Old-Fashioned, named for the southern Mexican city that's particularly famous for its Day of the Dead celebrations.
Based on tequila with a hint of smoky mezcal, it showcases not one but two indigenous Mexican liquors.
