Ingredients
Method
Preparation
- Preheat oven to 350 degrees F (175 degrees C). Use an ungreased 10 inch tube pan with a removable bottom.
- In a medium bowl, sift together cake flour, 1/2 cup granulated sugar, and salt. Set aside.
Mixing the Batter
- In a large mixing bowl, beat egg whites until foamy.
- Add cream of tartar and beat until soft peaks form. Gradually add remaining granulated sugar until firm, glossy peaks are achieved.
- Fold in lemon zest and vanilla extract.
- Gently fold in the dry ingredients in three additions.
- Toss blueberries with flour and fold into the batter.
Baking
- Spoon batter into the tube pan and bake for 35 to 45 minutes until golden brown and a skewer comes out clean.
- Invert the pan to cool upside down for at least 1 1/2 to 2 hours.
- Once cool, run a knife around the edges and invert onto a serving plate. Slice and serve.
Notes
Serve thin, airy slices to showcase the cake's open crumb. A light dusting of confectioners' sugar or a few extra fresh blueberries enhances the sensory experience. Store loosely covered at room temperature for up to 24 hours, or wrap and refrigerate up to 3 days.
