how to make Fresh Lemon Mousse
Ingredients:
- 1 stick unsalted butter, room temperature
- 1 cup granulated sugar
- 1 tablespoon fresh lemon zest
- Dash salt
- 4 large eggs
- 1/2 cup freshly squeezed lemon juice (about 4 lemons)
- 3 large whole eggs
- 3 large eggs, separated
- 1 cup plus 2 tablespoons granulated sugar
- 2 teaspoons lemon zest
- 1/2 cup freshly squeezed lemon juice, about 4 lemons
- Salt
- 1 cup heavy whipping cream
- 1/2 cup homemade lemon curd, room temperature
- 1 cup heavy whipping cream, cold
- 1/3 cup powdered sugar
- 1/2 teaspoon pure vanilla extract
Directions:
-
Start by zesting the lemons. Be careful to only get the yellow part, avoiding the white pith. Set the zest aside. Cut the lemons in half and juice them to get 1/2 cup of lemon juice.
-
In a large mixing bowl, cream the room temperature butter using a stand mixer or hand mixer. Mix in the granulated sugar, dash of salt, and lemon zest until well combined.
-
Crack the eggs into a small bowl, removing any Chalaza (the white strands attached to the yolks). Add each egg carefully into the mixing bowl, mixing thoroughly after each addition. Then add the lemon juice and a pinch of salt, mixing again to combine.
-
Transfer this mixture into a medium saucepan and cook over low heat. Stir constantly until the mixture thickens, which takes about 8 to 10 minutes. Once thickened, remove from heat and let it cool to room temperature. Cover the top of the lemon curd with plastic wrap to prevent a skin from forming.
-
In a large heatproof bowl, combine 3 whole eggs, 3 egg yolks, 1 cup of sugar, lemon zest, lemon juice, and a pinch of salt. Whisk together. Place this bowl over a saucepan of simmering water and continue to whisk for about 12 minutes until the mixture thickens like pudding. Remove from heat and cool for 15 minutes. Refrigerate for 1 to 2 hours until completely chilled.
-
Next, in a stand mixer bowl, add about 2/3 of the egg whites and a pinch of salt. Beat on high speed until soft peaks form. Gradually add 2 tablespoons of sugar, continuing to beat until stiff peaks form. Gently fold these egg whites into the chilled lemon mixture.
-
In the same mixing bowl (no need to clean), add cold heavy whipping cream. Beat on medium-low speed until it starts to thicken, then increase to high speed. Beat until stiff peaks form. Carefully fold this whipped cream into the lemon mixture, followed by the lemon curd.
-
Pour the final mixture into a 7-inch diameter x 3-inch deep souffle dish. Chill for at least 1 hour.
-
For the whipped cream topping, add heavy whipping cream to a mixing bowl and beat on medium-low speed until slightly thickened. Add powdered sugar and vanilla extract, then beat on high speed until stiff peaks form. You can pipe or dollop the whipped cream over the mousse surface. Optionally, add small lemon slices for garnish.
-
Serve the mousse cold and refrigerate any leftovers for up to 5 days. If you want to freeze it, it can last for up to 3 months. Just remember not to add whipped cream until you are ready to serve!
