Ingredients:
- 1.25 cups (160g) Gluten-Free All-Purpose Flour Blend (with xanthan gum)
- 1.5 cups (300g) Superfine Sugar, divided
- 0.25 cup (30g) Cornstarch or Arrowroot Powder
- 0.5 tsp Fine Sea Salt
- 1.5 cups Egg Whites (approximately 10–12 large eggs), chilled
- 1.5 tsp Cream of Tartar
- 2 tsp Pure Vanilla Extract
- 0.5 tsp Pure Almond Extract
Instructions:
- Preheat and Prep: Set your oven to 180°C (350°F). Ensure your tube pan is bone dry and completely ungreased.
- Sift the Dry Base: Whisk together the 160g GF flour, 0.75 cup of the superfine sugar, 30g cornstarch, and salt. Sift this mixture three times.
- Begin the Meringue: Place the 1.5 cups chilled egg whites and 1.5 tsp cream of tartar in your clean bowl. Beat on medium low until the surface is covered in tiny, uniform bubbles.
- Build the Foam: Increase speed to medium high. Add the remaining 0.75 cup sugar one tablespoon at a time. Continue beating until stiff, glossy peaks form that stand straight up when the whisk is lifted.
- Add Aromatics: Gently whisk in the 2 tsp vanilla and 0.5 tsp almond extract during the final seconds of whipping.
- The First Fold: Sprinkle about one quarter of the flour mixture over the whites. Use a large rubber spatula to cut down the center and scoop up the bottom, rotating the bowl.
- Incorporate the Rest: Repeat the folding with the remaining flour in three more additions. Fold only until no dry streaks remain to avoid deflating the air.
- Fill the Pan: Spoon the batter into the tube pan. Gently run a knife through the batter in a circle to pop any large air pockets.
- The Golden Bake: Bake for 40 minutes. The cake is done when the top is golden brown and the cracks look dry.
- The Gravity Trick: Immediately invert the pan onto its feet (or over a bottle neck). Let it cool completely upside down for 2 hours before removing.
