Position a rack in the center of the oven. Preheat the oven to 400┬░F. Grease a standard 12-muffin pan or line with paper cups.
Whisk together thoroughly:
1 1/2 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon ground cinnamon
1/2 teaspoon salt
1/2 teaspoon ground nutmeg
1/4 teaspoon ground cloves
1/4 teaspoon ground allspice
Whisk together in a large bowl:
2 large eggs
3/4 cup sugar
Stir in and let stand for 10 minutes:
1 1/2 cups packed finely shredded carrots
Stir in:
1/4 cup orange juice
5 tablespoons warm melted unsalted butter or vegetable oil
1/2 cup coarsely chopped walnuts or pecans
1/2 cup golden raisins
Add the flour mixture and fold just until the dry ingredients are moistened. Do not overmix; the batter should not be smooth. Divide the batter among the muffin cups. Bake until a toothpick inserted in 1 or 2 of the muffins comes out clean, 15 to 18 minutes. Let cool for 2 to 3 minutes before removing from the pan. If not serving hot, let cool on a rack. Serve as soon as possible, preferably the day they are baked.
