Ingredients
Method
Preparation
- Preheat your oven to 350°F (175°C) and position a rack in the lower third of the oven.
- In a bowl, sift 1 cup of cake flour with 3/4 cup of granulated sugar. Set aside.
Mixing
- In a large bowl, combine 10 egg whites with cream of tartar and salt. Beat on medium speed until frothy and soft peaks form.
- Gradually add the remaining 3/4 cup of granulated sugar, mixing until stiff, glossy peaks form. Gently fold in vanilla extract and key lime zest.
- Carefully fold the dry flour mixture into the meringue three times, being cautious not to deflate the whites.
- Fold in 2 tablespoons of key lime juice, ensuring it's evenly distributed.
Baking
- Pour the batter into an ungreased 10-inch tube pan, smoothing the top gently.
- Bake for 35 to 40 minutes until golden and springs back when lightly pressed.
- Once baked, invert the pan onto a bottle or funnel and let cool completely for about 1 hour.
Glaze and Serve
- Whisk together confectioners sugar, remaining 2 tablespoons of key lime juice, and 2 tablespoons of milk until smooth.
- Run a knife along the edges of the cake to release it from the pan. Transfer to a serving plate and drizzle glaze over the top.
Notes
Ensure no yolk sneaks into your egg whites. The cake is best consumed within 2 days at room temperature, up to 1 week in the fridge, or can be frozen for up to 3 months. For a healthier glaze, use light whipping cream or yogurt mixed with lime juice.
