Queimada (drink)
Queimada is an alcoholic beverage of Galician tradition.
Queimada is a punch made from Galician augardente ( Orujo Gallego) - a spirit distilled from wine and flavoured with special herbs or coffee, plus sugar, lemon peel, coffee beans and cinnamon. It is traditionally prepared in a hollow pumpkin.
Typically, while preparing the punch a spell or incantation is recited, so that special powers are conferred to the queimada and those drinking it. Then the queimada is set alight, and slowly burns as more brandy is added.
