Line baking sheet with parchment or grease. In a large bowl, cream together shortening and sugar; add egg, orange zest, and juice. Mix well. Sift together flour, baking powder, salt, cinnamon and nutmeg. Add to creamed ingredients. Stir in raisins, candied fruit and nuts. Shape dough into a strip roughly 7x12 (mine was more like 5x12) and bake for 12 minutes. Remove from oven; cool slightly, then frost with glaze while warm. Sprinkle with colored sugar if desired. Cut into strips.
Glaze: Whisk together all ingredients until smooth.
Makes about 20, once you've eaten away the scraps.
