Orange Chiffon Cake (Source: Maida Heatter's Cakes (Andrews & McMeel Publishing, 2011 ed., pg. 28).
I wasn't familiar with the history of the chiffon cake until I read about it in Maida's book. An insurance salesman and hobbyist baker by the name of Henry Baker invented the recipe in 1927. It took Hollywood by storm and he provided celebrities and restaurants with specially made cakes for twenty years. In the late 40s, he sold the recipe to General Mills (Betty Crocker ) and they later revealed it's unique secret - vegetable oil as opposed to butter or shortening.
The cake is delicious and easy to make. When folding the egg yolk mixture with the egg whites, you don't want to overdo it and deflate the consistency. You also want to whip the egg whites past the peak stage but not until they are dry. Also, do not substitute the orange juice with lemon juice or the cake will fall.
The cake is very tall and light in texture. The whipped cream chocolate frosting is entirely optional but I can tell you that it compliments the cake nicely (the combination of orange and chocolate is one of my favorites).
Cake
2 cups sifted all-purpose flour
1 1/2 cups granulated sugar
3 tsp. baking powder
1 tsp. salt
1/2 cup vegetable or canola oil
7 large eggs, separated
Finely grated rind of 2 lemons
Finely grated rind of 3 oranges
3/4 cup orange juice
1/2 tsp. cream of tartar
Chocolate Whipped Cream Icing (optional)
2 cups heavy cream
1 cup sifted confectioners sugar
1/2 cup unsweetened cocoa powder (preferably Dutch process)
Pinch of salt
1/2 tsp. vanilla extract
Preheat the oven to 325 degrees. You will use a 10x14" Angel Food pan (the kind that comes apart in two pieces). Do not butter the pan.
Whisk together the flour, sugar, baking powder, and salt. Use a spatula to make a trench in the middle of the bowl. Add the oil, egg yolks (reserving the whites), lemon and orange zest and the orange juice to the trench.
Whisk the mixture together with the flour until it is smooth.
Beat the egg whites with the cream of tartar until they hold a stiff peak.
Fold 3/4 of the egg yolk mixture into the whites. Then fold the whites into the remaining yolk mixture. Just do this until the mixture is combined - do not overbeat it.
Pour the batter into the cake pan and bake for 55-60 minutes. (Note: Maida says to increase the oven temperature to 350 and bake an additional 10 or 15 minutes but I do not believe this is necessary. My cake was done after the initial 55 minute baking at 325. Press the top of the cake and it should bounce back slowly if it is done.)
Hang the pan upside down on a bottle neck or a funnel and allow it to cool completely.
After it has cooled, you can remove it carefully from the pan by running a sharp knife around the perimeter of the pan and the center section. Or you can freeze the cake - if freezing, leave it in the pan and wrap it in aluminum foil.
You can sprinkle the cake with confectioners sugar or opt to cover it with the following frosting (you can also use the frosting as a sauce on the side) -
Chill your mixer bowl and the whisk beater in the freezer (it only takes 5 or 10 minutes). Now whip all the ingredients (heavy cream, confectioners sugar, cocoa, salt and vanilla extract) together until it holds a shape. Frost the cake and you will need to refrigerate it. Maida also says that strawberries are nice to add as a garnish.
