“Hyper rapide, inratable” : Mercotte partage sa recette du gâteau de Savoie

Chef Nicolas Paciello and food writer Mercotte recently put a fresh spin on the classic Gâteau de Savoie. Their quick, airy version is ideal for bakers who want a delicate dessert that travels well and keeps for days. Read on for a clear, tested method to make this timeless French sponge at home.

Ingredients for a light Savoy sponge (Gâteau de Savoie)

  • 5 eggs, preferably at room temperature
  • 100 g caster sugar
  • 85 g plain flour
  • 30 g cornstarch (maize starch)
  • Zest of 1 lemon
  • Icing sugar, for dusting
  • Soft butter, for greasing the pan

Step-by-step method to bake the Savoy cake

  1. Grease your cake pan thoroughly with soft butter. Sprinkle a thin layer of sugar and turn the pan to coat the sides and bottom evenly.
  2. Separate the eggs, placing yolks in one bowl and whites in another. Keep bowls dry and spotless.
  3. Beat the egg whites until they are frothy. Gradually add about 35 g of the sugar while whisking, until the whites hold glossy peaks that slightly bend at the tip.
  4. Sift the flour and cornstarch together. This lightens the dry mix and prevents lumps.
  5. Whisk the egg yolks with the remaining sugar until pale and slightly thickened. Fold the yolks gently into the whipped whites for a short time to combine.
  6. Add the sifted flours in two additions. Use a gentle folding motion from the bottom up to keep as much air as possible in the batter.
  7. Stir in the lemon zest. Feel free to swap zest for orange, vanilla, or a touch of cocoa to vary the flavor.
  8. Pour the batter into the prepared pan. Tap the pan lightly to level the surface, then transfer to a preheated oven set to 175°C.
  9. Bake for about 30 minutes. Check doneness by inserting a thin knife; it should come out clean or with a few dry crumbs.
  10. Let the cake cool for a few minutes in the pan, then unmold. Once fully cool, dust generously with icing sugar before serving.

Practical tips and flavor ideas to improve results

  • Don’t overbeat the whites. Too-stiff peaks make the crumb dry instead of tender.
  • Sift dry ingredients for the lightest texture.
  • Room temperature eggs incorporate more air and produce a finer rise.
  • Use a deep, straight-sided mold to help the cake develop height.
  • For variations:

    • Orange zest instead of lemon for a sweeter profile.
    • A teaspoon of vanilla extract for a classic twist.
    • Fold in crushed praline or a tablespoon of cocoa for texture and depth.

Storage and serving suggestions

  • This sponge keeps well for several days if stored in an airtight container.
  • Serve plain, with jam, or topped with whipped cream and fresh fruit.
  • For travel, wrap the cake in parchment and keep it in a rigid tin to protect its shape.
