Classic Sponge Cake

👨‍🍳 Method

To assemble

1. 1
   Preheat the oven to 170°C (340°F) and grease a round pan 24 cm in diameter.

   ⚙ Preheating the OvenOven

   💡Put things in the oven only once it's reached temperature, after the heating light has gone off: an oven that hasn't reached temperature changes baking times, and the bake burns outside or stays underbaked.
2. 2
   Whip the eggs and sugar 8–10 minutes, until the mixture is pale, thick and very fluffy.

   💡Room-temperature eggs whip better than cold eggs. Take them out of the fridge 30 minutes before baking. Warm eggs also make a more stable foam that holds up in the oven.
3. 3
   Sift the flour and baking powder over the top and Fold gently, just until the flour is absorbed.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there are no streaks: vigorous mixing knocks the air out of the foam. Add whipped mixtures in stages: a quarter first, to lighten the mixture.

   💡Fold with a spatula, in broad strokes from the bottom up, and stop when there's no dry flour: vigorous mixing of a batter with flour develops gluten.

   💡Check by the cue (until…), not just the clock: every oven bakes a little differently.
