Perfect Genoise: Easy Recipe with 3 Ingredients (Pro Tips Included)

```html

What is a Genoise?

A genoise is the fundamental biscuit of French pastry, an essential base for many classic cakes like the strawberry cake, raspberry cake, or opera cake. This light and airy preparation often intimidates amateur bakers: who hasn’t experienced the frustration of a dense, flat, or collapsing genoise after baking?

Today, I share all my secrets to successfully making a perfect genoise every time, even for the CAP pastry exam!

Essential Ingredients

The beauty of a genoise lies in its simplicity: only 3 ingredients are needed:

• 4 eggs (at room temperature for better emulsification)
• 125g of sugar (classic semolina sugar)
• 125g of flour (T45 or T55, sifted for more lightness)

This classic 1:1:1 ratio (weight of eggs:sugar) is the traditional recipe taught in French pastry schools.

Perfect Tech: Genoise Robot vs Bain-Marie

The preparation method of a genoise even divides professionals. Contrary to popular belief, scientific studies have proven that the bain-marie does not significantly improve the texture or final volume of the genoise.

For the CAP pastry exam, I recommend the traditional bain-marie technique:

1. Beat the eggs and sugar in a bowl until it reaches 40°C
2. Continue beating with the robot until the mixture is completely cooled down

For home preparation, the direct robot technique is perfectly adapted and gives excellent results without unnecessary complications.

Detailed Prep Steps

The success of a perfect genoise begins with an impeccable egg-sugar mixture:

1. Place the whole eggs and sugar in the mixing bowl of the pastry robot
2. Beat at maximum speed for about 20 minutes
3. The mixture should triple in volume and become very frothy and pale
4. The "ribbon" is achieved when the mixture forms a thick, clear ribbon that remains visible on the surface for a few seconds

This crucial step incorporates the air necessary for the final lightness of the biscuit. An insufficiently beaten mixture will result in a dense and flat genoise.

Delicate Incorporation of Flour

The delicate incorporation of flour is the next crucial step:
