"My Grandma used to make these cookies all the time, and I grew up hooked! You'll be surprised at how great the combination of flavors are, especially with the citrusy glaze."
1Preheat the oven to 375 degrees F (190 degrees C). Grease cookie sheets.
2In a large bowl, cream together the shortening and sugar until light and fluffy. Add the eggs one at a time, beating well with each addition, then stir in the vanilla and carrots. Combine the flour, baking powder and salt; gradually stir into the creamed mixture. Finally, fold in the walnuts. Drop by rounded spoonfuls onto the prepared cookie sheet.
3Bake for 8 to 10 minutes in the preheated oven, until lightly golden. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack to cool completely.
4To make the glaze, put 1 cup of the confectioners' sugar into a medium bowl. Grate the rind of the orange into the bowl with the sugar. Squeeze in enough juice from the orange to form a thin but spreadable consistency. Mix until smooth. If necessary, stir in more confectioners' sugar. Spread onto the cooled cookies. Store in an airtight container.
