In this article, we will guide you through the step-by-step process of creating this delightful dessert.

Gathering the Ingredients

Before diving into the recipe, it is essential to gather all the necessary ingredients. Here’s what you’ll need:

  • 4 large lemons
  • 1 cup of granulated sugar
  • 4 eggs
  • 1 cup of heavy cream
  • 1 teaspoon of vanilla extract
  • A pinch of salt

Preparing the Lemon Mousse

Now that you have all the ingredients ready, let’s start making the lemon mousse:

Step 1: Zesting and Juicing the Lemons

Begin by zesting the lemons to extract their fragrant outer layer. Use a fine grater or a zester to carefully remove the yellow zest, making sure to avoid the bitter white pith. Set the zest aside for later use.

Next, cut the lemons in half and squeeze out their juice. You will need approximately 1/2 cup of fresh lemon juice for this recipe. Strain the juice to remove any seeds or pulp.

Step 2: Preparing the Lemon Mixture

In a heatproof bowl, whisk together the lemon zest, lemon juice, sugar, eggs, and a pinch of salt. Place the bowl over a saucepan of simmering water, creating a double boiler. Make sure the bottom of the bowl does not touch the water.

Continue whisking the mixture constantly until it thickens and reaches a custard-like consistency. This process may take around 10-15 minutes. The heat from the simmering water will gently cook the eggs and thicken the mixture.

Step 3: Cooling and Chilling

Once the lemon mixture has thickened, remove it from the heat and let it cool to room temperature. This step is crucial to prevent the cream from curdling when added later.

In a separate bowl, whip the heavy cream and vanilla extract until soft peaks form. Gently fold the whipped cream into the cooled lemon mixture, ensuring that they are well combined.

Transfer the lemon mousse into individual serving dishes or a large serving bowl. Cover the dishes with plastic wrap and refrigerate for at least 2 hours, or until the mousse sets and becomes firm.

A5: Yes, you can use alternative sweeteners like honey or maple syrup. However, keep in mind that they may alter the texture and taste of the mousse slightly.
