Use room-temperature eggs: They whip more easily and help create a stable, airy batter.
Sift the flour: This prevents lumps and produces a smoother cake texture.
Do not overmix: Gentle folding preserves the air needed for a light sponge.
Use a gentle oven temperature: Castella Cake needs slow, even baking to cook properly without becoming dry.
Avoid opening the oven: Opening the door too early can cause the cake to collapse.
Refrigerate before slicing: Chilling helps the cake develop a moist, tender texture and makes cleaner slices.
