Ingredients:
- 1 cup (120g) cake flour
- 1 1/2 cups (300g) superfine sugar
- 1/4 teaspoon (1.5g) fine salt
- 12 large egg whites (approx. 360ml), room temperature
- 1 1/2 teaspoons (5g) cream of tartar
- 1 tablespoon (15ml) vanilla bean paste
Instructions:
- Preheat your oven to 325°F (163°C).
- Sift the cake flour, salt, and the first half of the sugar together into a bowl. Sift them a second time to ensure maximum aeration and set aside.
- In a clean metal bowl, beat the egg whites and cream of tartar on medium speed until foamy.
- Gradually increase to high speed and slowly add the remaining sugar. Continue beating until stiff peaks form (peaks stand straight up without drooping).
- Stir in the vanilla bean paste at the very end.
- Spoon a third of the flour mixture over the egg whites. Using a rubber spatula, gently fold the flour in using a 'cut and turn' motion. Repeat with the remaining flour mixture until just combined.
- Pour the batter into an ungreased 10-inch aluminum tube pan.
- Bake for 40 minutes.
- Immediately invert the pan and allow the cake to cool upside down for 1 hour before removing from the pan.
