Beat one pound of butter to a cream; add gradually one pound of granulated sugar, and when very light add four eggs well beaten. Dissolve a teaspoonful of bicarbonate of soda in two tablespoonfuls of warm water, add it to one cupful of molasses, and then add the molasses to the butter, sugar and eggs. Stir in half a pint of lukewarm, strong, black coffee, three cupfuls of flour, a level teaspoonful of allspice, half a teaspoonful of cloves, two teaspoonfuls of cinnamon and one nutmeg, grated. Beat thoroughly. Mix half a pound of shredded citron, two pounds of stoned raisins and one pound of currants; flour them with a cupful of pastry flour, stir them in carefully, and finally bake in fruit cake-pans in a slow oven for two hours and a half.
