Grease and
line with greased brown paper four 9 x 5 x 3-inch (23 x 12.5 x 7.5-cm)
loaf pans. Put a pan of hot water in bottom of oven. Sift flour, spices
and salt together onto waxed paper. Combine fruit and nuts in large
bowl. Measure out 1 cup (250ml) of the flour-spice mixture, add to the
fruit and nuts and blend well. Cream butter and sugar until fluffy. Add
egg yolks, one at a time, beating well after each addition. Continue
beating until smooth and creamy. Blend in remaining flour mixture
alternately with sherry or coffee, grape juice, orange juice and lemon
juice, beginning and ending with flour mixture. Blend in grated orange
and lemon rinds and fruit-nut mixture. Heat oven to 250F (120C). Beat
egg whites until they hold stiff peaks. Fold into fruit mixture. Spoon
into prepared pans and bake about 3 hours or until a toothpick inserted
in the center comes out clean. Cool for a few minutes in pans then lift
out by ends of paper and finish cooling on cake racks. Strip off paper,
wrap tightly in aluminum foil and store in a cool dry place for several
weeks before using.
