2 tbsp canola oil
1 cup sugar
2 whole eggs
2 egg whites
1 cup whole wheat flour
1 cup unbleached flour

Preheat oven to 350.

In saucepan, bring orange juice and rind to a boil. Remove from heat and cool while proceeding with recipe.

In a mixer or by hand using a wire whisk in a large bowl, mix oil and sugar until creamy. Add eggs and egg whites one at a time. Continue beating until all the eggs are added.

In a separate bowl, combine flours and baking soda, and add to the oil, sugar, and egg mixture.

Add flour mixture to orange juice mixture, a third at a time, until just combined. Pour into a 10 inch tube pan lightly sprayed with Pam.

Bake for 35-40 minutes until a toothpick inserted in the center comes out clean.
