Classic Genoise

This recipe guides you through creating a classic Genoise, a light and airy sponge cake known for its delicate texture. It relies on whipping eggs and sugar into a stable foam, which provides the cake's structure without leavening agents. Perfect as a base for layered cakes or trifles, this intermediate-level bake requires careful technique for success.

Equipment

  • 1 Large Mixing Bowl Heatproof for double boiler
  • 1 1-Quart Saucepan For the double boiler setup
  • 1 Candy Thermometer Crucial for precise egg foam temperature
  • 1 Electric Mixer Handheld or stand mixer with whisk attachment
  • 1 Rubber Spatula For delicate folding

Ingredients
  

Main

  • 8 large eggs
  • 3 large egg yolks
  • 1 cup granulated sugar
  • 2 1/2 tablespoons honey
  • 2 cups unbleached unbromated pastry flour, sifted

Instructions
 

  • Place a 1-quart saucepan half filled with water over high heat and bring it to a simmer. Make a double boiler by setting a large mixing bowl over the simmering water. Place the whole eggs, egg yolks, sugar, and honey in the mixing bowl and make an egg foam by whisking the mixture to 113 degrees on a candy thermometer, about 7 to 10 minutes. The egg foam passes through various stages becoming foamy, then smooth and finally it thickens. When it is thick, it will be hot to the touch, tripled in volume, and light in color and the sugar will have completely dissolved. If you dip the whisk into the mixture and pull it out, the batter should fall back into the bowl in a thick ribbon.
  • Remove the mixing bowl from the heat and whip the batter with an electric mixer on medium-high speed until it cools, increases in volume, stiffens slightly and becomes pale yellow, about 7 to 10 minutes. Take the time to whip it well; if the mixture is under whipped, the baked genoise will be dense. Very, very carefully, fold in the flour with a rubber spatula until the flour is no longer visible, making sure to fold to the bottom of the bowl. Do not over mix or the batter will deflate. Fill buttered and parchment paper-lined 8-inch round cake pans 3/4 full with batter. Bake in a preheated 350 degree F oven until well-risen and golden brown, about 30 minutes.
  • Let the genoise cool slightly. Unmold, remove parchment paper and finish cooling on a wire rack. The baked genoise can be stored in the freezer for 2 to 3 weeks if well wrapped in plastic wrap. Return it to room temperature before using it.
  • VARIATION: Make this recipe into a Chocolate Genoise by substituting unsweetened cocoa powder for 10 to 20 percent of the weight (a scant 1/4 cup to a full 1/3 cup) of the flour. Weigh the cocoa powder before you sift it.
  • Jacques' Tip: Genoise can be made with butter. In this recipe, you can substitute butter (5 1/2 tablespoons) for the 3 large egg yolks. Melt and cool the butter and fold it in after the flour is added.

Notes

Achieving the correct egg foam is paramount for a light Genoise; precise temperature control (113°F) and thorough whipping post-heat are non-negotiable for volume and stability. Under-whipped batter will yield a dense cake. When folding in flour, do so gently and minimally to retain all the air incorporated, avoiding deflation. Over-mixing will knock out the air, resulting in a tough crumb. For a richer flavor, consider Jacques' tip of substituting some egg yolks with melted and cooled butter, folding it in carefully after the flour. Ensure your oven is accurately preheated to maintain even baking and a golden crust.
