Cranberry Muffins

In a large bowl, combine the flour, sugar, baking powder, nutmeg, cinnamon, baking soda, ginger, salt and orange zest. Cut in shortening until crumbly. In a small bowl, combine the orange juice, eggs and vanilla. Stir into dry ingredients just until moistened. Fold in cranberries and nuts., Fill 18 greased or paper-lined muffin cups two-thirds full. Bake at 375° until a toothpick inserted in the middle comes out clean, 18-20 minutes. Cool in pans for 10 minutes before removing to wire rack. Serve warm.
