Orange Chiffon Cake

Recipe taken from Florence, always trusted. My chiffon fever is not over yet. Will be making more variety in time to come.

I had overbaked the cake a little, hence it actually turn out to be quite dry. Original uses a 20cm chiffon tube pan, but I only got 21cm. Hence actually need to reduce the baking time by about 5-10mins and I forget about it. I am not a big fan of orange chiffon, hence in terms of taste wise, I find it so so only. I can't remember if I did take any picture. Will post the pictures if I find them.
