A soul cake is a small round cake which is traditionally made for All Hallows' Eve, All Saints' Day and All Souls' Day to commemorate the dead in the Christian tradition. The cakes, often simply referred to as souls, are given out to soulers who go from door to door during the days of Allhallowtide singing and saying prayers "for the souls of the givers and their friends". The practice in England dates to the medieval period, and was continued there until the 1930s, by both Protestant and Catholic Christians. The practice of giving and eating soul cakes continues in some countries today, such as Portugal, and in other countries, it is seen as the origin of the practice of trick-or-treating. In Lancashire and in the North-east of England they are also known as Harcakes. In the United States, some churches, during Allhallowtide, have invited people to come receive sweets from them and have offered "pray for the souls of their friends, relatives or even pets" as they do so. Among Catholics, traditionally the soul cakes are blessed by a priest before being distributed on the Eve of All Saints (Hallowe'en); in exchange, the children promise to pray for the souls of the deceased relatives of the giver during the month of November, which is a month dedicated especially to praying for the Holy Souls In Purgatory. Any leftover soul cakes are shared among the distributing family.
