Yay, orange’s season is still in the air! I realized I only bake with orange as the ingredient every December or January. In 2006, I made Orange Soufflé and this January 2008, I made two dishes, Cashew Orange Biscotti and Orange Angel Loaf Cake.
Actually I made this angel loaf cake on purpose to take pictures of egg white beaten as requested by mbak Lita. She had been curious about it since I used ready to use egg whites in tetra-pack. It’s easy to find egg whites in tetra-pack at grocery stores here, I also noticed some restaurants/cafes have egg whites omelettes in their menu.
As a recipe of Pandan Angel Loaf Cake that I posted here, it’s also modified recipe from “Sugar” by Anna Olson. This Orange Angel Loaf Cake had been made twice. First time, I used flour and sugar as much as the recipe noted and also added 1/4 cup of orange juice and 1 teaspoon of orange zest. The result, it tasted too sweet. At the second time, I modified by adding more flour to 2/3 cup, reducing the sugar and adding squeezed orange and orange zest as much as the first trial.
150 ml egg whites
1/2 tsp cream of tartar
1 pinch salt
7 tbsp sugar (original recipe uses 1/2 cup (8 tbsp) sugar)
1/4 cup orange juice
1 tsp orange zest
2/3 cup cake and pastry flour
3 tbsp sugar (original recipe uses 1/4 cup (4 tbsp) sugar)
Preheat oven to 375 F
Whip egg whites with cream of tartar and salt until they are foamy. Gradually pour in 7 tbsp of the sugar while whipping and continue to whip until whites hold a stiff peak (they should stand straight when batters are lifted).
Stir in orange juice and orange zest. Fold flour and sugar sifted into whites gently but quickly in 3 additional.
Scrape batter into an ungreased a half loaf pan and run a knife through batter to remove any large bubbles.
Bake 20 to 25 minutes, until a tester inserted in the centre of the cake comes out clean. Invert pan and let cake cool completely*.
* The best way to cool a cake in a loaf pan upside down? Place the loaf pan in a large bowl, so the pan sits without the cake touching the bottom
