This is a recipe that I found on the Joy of Baking and I made it for our Wednesday night dinner at church and everyone loved it. I made fresh berries and cream as a compliment to go with the cake. I also added 1/4 cup mayonnaise to the recipe which the original didn't call for but I do that for almost all of my cakes to make them very moist. Also the orange zest and lemon zest are optional. I added the lemon and it made it taste pretty much like a lemon cake so if you don't want the fruit flavor I would omit the zest or only use a small amount like 1/2 a teaspoon. To make your own superfine sugar, place 3 cups granulated white sugar in a food processor. Process until very fine, about 30 seconds.
