Heat the oven to 185 degrees. Wash the orange well, chop off ends. Cut into 8 slices, take out the seeds and core and grind in a food processor. Set aside. (You could also use a mince meat grinder for this step.)

In a mixing bowl, sift the flour, baking powder, baking soda, cinnamon, nutmeg and salt. Add the sugar and mix.

Add orange purée and oil. Mix well.

Beat eggs separately, add and mix well.

Add the carrots and nuts. Fold in well. The batter will be quite runny. Pour into greased pan of your choice. I used 2 nine inch cake pans. Bake for 50 - 60 minutes. Cool completely before icing and decorating. Yum! Enjoy!
