Preheat oven to 300°.
Lightly spoon flour into dry measuring cups, and level with a knife. Combine the flour and the next 4 ingredients (flour through mace) in a large bowl. Beat the sugar, vanilla, and eggs with a mixer in a large bowl at medium speed until thick. Stir in the flour mixture, cashews, and raisins. Turn the dough out onto a lightly floured surface, and knead lightly 7 or 8 times. Shape dough into a 12-inch roll. Place roll on a baking sheet coated with cooking spray, and pat to 1-inch thickness. Bake at 300° for 45 minutes. Cool 10 minutes on a wire rack.
Cut roll diagonally into 24 (1/2-inch) slices; stand the slices upright on baking sheet. Bake for 20 minutes (the cookies will be slightly soft in center but will harden as they cool). Remove from baking sheet; cool completely on wire rack.
