Mastering the Genoise Sponge
The Genoise is the backbone of classic pâtisserie, prized for its ability to hold its shape while remaining tender. It requires patience and a light hand, specifically during the folding stage where you risk losing the air you worked so hard to trap.
Temperature control is your primary tool
Ensure your eggs are at room temperature before starting, and never exceed 115°F during the warming phase; otherwise, you risk cooking the eggs prematurely.
- Stand mixer with whisk attachment
- Heat-proof glass or metal bowl
- Saucepan
- 9-inch round cake pan
- Rubber spatula
- Sifter
What goes in.
- 4 largeeggs, room temperature
- 125ggranulated sugar
- 125gcake flour, sifted twice
- 40gunsalted butter, melted and cooled to lukewarm
- 1 tspvanilla extract
Trapping the air
When lifting the whisk, the batter should fall back onto itself and hold a visible trail on the surface for several seconds before sinking back into the mixture.
The method.
Prepare the pan
Grease the pan, line the bottom with parchment paper, and dust the sides with flour, tapping out the excess.
Warm the base
Place the eggs and sugar in a bowl over a saucepan of simmering water. Whisk constantly until the sugar is dissolved and the mixture feels warm to the touch.
Aerate
Transfer to a stand mixer and whisk on high speed until the mixture triples in volume, thickens significantly, and turns pale ivory.
Incorporate dry ingredients
Sift the flour over the egg foam in three batches. Using a wide rubber spatula, fold gently by cutting down the center and sweeping around the bottom, rotating the bowl as you go.
Add the fat
Pour the cooled melted butter down the side of the bowl. Fold quickly but carefully until just combined, ensuring no butter pools at the bottom.
Bake
Pour into the prepared pan and bake at 350°F for 25 minutes. The cake is done when the top springs back when pressed and the edges begin to pull away slightly from the pan.
Other turns to take.
Chocolate Genoise
Replace 25g of the cake flour with 25g of high-quality unsweetened cocoa powder.
Citrus Genoise
Add the zest of one lemon or orange to the sugar before whisking with the eggs.
When it doesn't go to plan.
Always sift your flour twice to ensure it is light and free of lumps, which helps prevent over-mixing.
If the batter starts to deflate, you have worked it too long; stop folding immediately.
Let the cake cool in the pan for five minutes before inverting it onto a wire rack to finish cooling.
The ones that keep coming up.
Why did my sponge sink in the middle?
This usually indicates the oven temperature dropped when the door was opened, or the flour was folded in too aggressively, crushing the air bubbles.
Can I substitute all-purpose flour?
Cake flour has a lower protein content, which is essential for the delicate crumb of a Genoise. All-purpose flour will result in a tougher, denser cake.
