In a saucepan over medium high heat combine; the sugar, shortening, ground cinnamon, ground nutmeg, ground allspice, salt, raisins, and water bring to a boil and continue boiling for 5 minutes. Remove from heat and let cool.
Sift the flour, baking powder and baking soda together. Add the flour mixture to the cooled raisin mixture. Stir until just combined. Pour batter into prepared pan.
