🛒 Ingredients for Perfect Castella Cake

• Medium Eggs — The cake’s backbone, providing volume and richness

• Granulated Sugar — Sweetens and aerates when whipped with eggs

• Honey — Adds moisture, subtle sweetness, and a golden crust

• Cake Flour — Ensures a fine, soft crumb with low protein content

👩‍🍳 Step-by-Step Guide to Baking Castella Cake

1. Prep
   Preheat oven to 325°F (165°C). Line a 9×5 inch loaf pan with parchment paper.

2. Whisk Eggs & Sugar
   Beat eggs and sugar vigorously until light, fluffy, and forming a slow-ribbon when lifted (called the ribbon stage).

3. Add Honey
   Gently fold honey into the egg mixture, preserving airiness.

4. Incorporate Flour
   Sift cake flour in stages, folding carefully to keep batter airy without overmixing.

5. Bake
   Pour batter into pan, smooth top, tap to release air bubbles. Bake 45–50 minutes, until a toothpick comes out clean.

6. Cool
   Let cake cool in pan for 10 minutes, then transfer to a wire rack to cool completely.

💡 Pro Tips for the Perfect Castella Cake

• Use room temperature ingredients for even mixing.

• Achieve the ribbon stage by whisking until the batter falls slowly off the whisk.

• Avoid opening the oven door early to prevent collapse.

• Tap the pan before baking to remove large air pockets.
