In Brazil, Christmas is celebrated on the evening of the 24th. It is when all the family gather for the main Christmas meal and presents are opened at midnight. The next day (25th), most families will have the left over for lunch, or sea food.
Turkey is the usual option for the Brazilian Christmas as it is very traditional. It is usually served with fruits, farinha de mandioca, and white rice. For dessert you can make a portuguese “rabanadas” or panetone
