6 large eggs, separated plus 1 (30 grams) additional egg white
2 1/4 cups (225 grams) sifted cake flour
1 1/2 cups (300 grams) superfine white (castor) sugar
1 tablespoon baking powder
1 teaspoon salt
1/2 cup (120 ml) vegetable oil or safflower oil
3/4 cup (180 ml) freshly squeezed orange juice (2 - 3 large Navel Oranges)
2 tablespoons (10 grams) orange zest
3/4 teaspoon cream of tartar ( I don't use it because I do not know from where to buy. Instead of it I use 2 tsp. of curd)
1 1/3 cups of Coconut
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 325 degrees F (170 degrees C) and have ready an angel food cake pan or a 10" two piece tube pan .
Combine together flour, sugar (minus 3 tablespoons (42 grams)), baking powder, and salt. Make a well in the center of the flour mixture and add the egg yolks, oil, orange juice, and orange zest. Beat about one minute or until smooth.
In a separate bowl, 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 or wire whisk, gently fold the egg whites into the batter just until blended (being careful not to deflate the batter). Add coconut and mix well.
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 and 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.
Can store in an airtight container for a few days at room temperature or for about a week in the refrigerator. This cake can also be frozen for a couple of months.
