In a large bowl, beat butter, sugar and eggs with an electric mixer until fluffy, adding eggs one at a time until yolk dissapears. Stir in flavoring.
Sift together next 4 ingredients and mix thoroughly with butter and egg mixture. Work the fruit and nuts into batter with hands. Grease and flour a 19" tube pan.
Fill pan 2/3 full with batter. Bake at 275° for 3 hours. One-half hour before cake is done, brush top with corn syrup. Decorate with pecan halves and finish baking. Cool. If desired, place cake, wrapped in a wine-soaked cloth, in an airtight container. Store in a cool place for several weeks; this blends and mellows the cake.
