I could not add all the flour because there was not enough liquid. In order to actually make a batter I had to add an extra egg and about 1/2 to 3/4 cups of water. The cake was a little denser than I had hoped but was very tasty. I think I would try to separate the eggs and beat the whites and fold them in to make it more light. I also cut the Mandarin orange slices in half and folded them in.. the recipe was unclear about draining the Mandarin oranges and maybe that was the liquid that was required that I did not use.
