Some good nuts to use in an old fashioned fruitcake recipe are pecans, Brazil nuts and walnuts, suggests the New York Times. Old-fashioned fruitcake is a cake filled with dried fruit and nuts and soaked in brandy. It is usually served during the Christmas season.
Fruitcake developed from the discovery that soaking fruits in sugar water could preserve them longer. The typical fruitcake recipe dates back to the 19th century. Nuts were added to the recipe by bakers in the southern United States who had access to large quantities of inexpensive nuts. Fruits often used in fruitcake include candied cherries, pineapple, apricots and raisins. However, recipes can be altered to suit a person's preferences by removing or changing the fruit and nut varieties.
