Orange Chiffon Cake
You'll need:
6 large eggs, separated plus 1 (30 g) additional egg white
2 1/4 C (225 g) sifted cake flour
1 1/2 C (300 g) superfine sugar*
1 tbsp baking powder
1/2 tsp salt
1 tsp pure vanilla extract
1/2 C (120 ml) vegetable oil
3/4 C (180 ml) freshly squeezed orange juice (2 - 3 large Navel Oranges)
2 tbsp (10 g) orange zest**
- Separate the eggs and place the whites in one bowl and the yolks in another. Cover with plastic wrap and bring them to room temperature (about 30 minutes).
- Preheat the oven to 325oF and have ready a 10 inch (25 cm) two piece tube pan (ungreased).
- In the stand mixer, fitted with the paddle attachment, place the flour, sugar (minus 3 tablespoons (42 grams) for later use), baking powder, and salt. Beat until combined.
- Make a well in the center of the flour mixture and add the egg yolks, oil, orange juice, orange zest, and vanilla extract. Beat about one minute or until smooth.
- In a separate bowl, with the whisk attachment, beat the egg whites until foamy.
- Add the cream of tartar and continue to beat until soft peaks form.
- Gradually beat in the remaining 3 tablespoons (42 grams) of sugar and beat until stiff peaks form.
- With a large rubber spatula, gently fold the egg whites into the batter just until blended (being careful not to deflate the batter).
- Pour the batter into the ungreased tube pan and bake for about 55 to 60 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. (When lightly pressed the cake will spring back).
- Immediately upon removing the cake from the oven invert the pan or place on a bottle or flat surface so it is suspended over the counter. Let the cake cool completely before removing from pan (about 1 1/2 - 2 hours).
- To remove the cake from the pan, run a long metal spatula around the inside of the tube pan and center core. Invert onto a greased wire rack.
Note:
*To make superfine sugar, process 1 1/2 cups (300 g) of granulated sugar in your food processor for about 30 seconds or until finely ground. Superfine sugar is used as it dissolves easier in the batter.
**Orange Zest - The orange outer rind of the orange that contains the fruit's flavor and fragrant.
***Cream of tartar is tartaric acid and is a fine white crystalline acid salt which is a by-product of the wine-making industry. It is used in the whipping of egg whites to stabilize them and allow them to reach maximum volume. HAPPY BAKING!
