Ingredients
For the Lemon Curd

- 1/2 cup freshly squeezed lemon juice, about 4 lemons
For the Lemon Filling

- 1 cup plus 2 tablespoons granulated sugar
- 2 teaspoons lemon zest
- 1/2 cup freshly squeezed lemon juice, about 4 lemons
- Salt

How to Make Fresh Lemon Mousse
Step 1: Prepare Lemons
Zest the lemons carefully to only remove the yellow part. Cut them in half and juice them, reserving 1/2 cup of juice for later use.
Step 2: Make Lemon Curd
Cream the butter in a large mixing bowl using a stand mixer or hand mixer. Add granulated sugar, salt, and lemon zest. Mix well until creamy.
Add the eggs one at a time while continuing to mix thoroughly after each addition. Then pour in the reserved lemon juice and mix until fully combined.
Transfer the mixture to a medium saucepan and cook on low heat while stirring constantly until thickened—this should take about 8-10 minutes. Remove from heat and let cool.
Step 3: Chill Curd
Spoon the cooled curd into a bowl and cover directly with plastic wrap to prevent a skin from forming. Allow it to cool completely at room temperature before using.
Step 4: Prepare Lemon Filling
In a large heatproof bowl, whisk together whole eggs, egg yolks, granulated sugar, zest, lemon juice, and salt until combined. Place this bowl over a pot of simmering water (double boiler method), whisking constantly until thickened like pudding—around 12 minutes.
Once thickened, cool for 15 minutes then cover with plastic wrap directly on top and refrigerate for 1-2 hours until chilled.
Step 5: Whip Egg Whites
Take about 2/3 of the egg whites (from separated eggs) and add them to a clean mixing bowl fitted with a whisk attachment. Add a pinch of salt and beat on high speed until soft peaks form. Gradually add the sugar while beating until stiff peaks develop.
Gently fold these egg whites into your chilled lemon filling using a rubber spatula by going under the filling and up along the sides gently.
Step 6: Fold in Whipped Cream
In the same mixing bowl (no need to clean), add cold heavy whipping cream. Beat on medium-low speed initially before switching to high speed once slightly thickened—continue beating until stiff peaks form.
Carefully fold this whipped cream into your combined lemon mixture until well blended. Finally, gently incorporate homemade lemon curd into this mixture.
Step 7: Chill Your Mousse
Transfer your complete mousse mixture into a souffle dish (7-inch diameter x 3-inch deep). Chill it in the refrigerator for at least an hour before serving.
Step 8: Top with Whipped Cream
For serving, whip additional heavy cream with powdered sugar and vanilla extract until stiff peaks form. Use either a piping bag or spoon dollops over the surface of your mousse just before serving.
Optional step includes garnishing with small quarter slices of lemon between whipped cream dollops for added decoration!
Enjoy your deliciously refreshing Fresh Lemon Mousse!

- Fold gently – When combining mixtures, fold gently to retain the lightness of the whipped cream and egg whites.
- Chill adequately – Allow the mousse to chill completely; this enhances its texture and flavor.
- Taste before serving – Adjust sweetness or tartness by adding more sugar or lemon juice based on personal preference.

Common Mistakes to Avoid
When making Fresh Lemon Mousse, it’s easy to run into some common pitfalls. Here are a few mistakes to keep in mind:
- Using cold ingredients: Ensure all your ingredients, especially the cream and lemon curd, are at room temperature for better incorporation.
- Overbeating the egg whites: Be careful not to overbeat the egg whites. Stop when you reach soft or stiff peaks to maintain the mousse’s airy texture.
- Skipping the cooling step: Allowing the lemon filling to cool properly ensures a smooth texture. Skipping this step can lead to a grainy mousse.
- Not folding gently: When combining whipped cream with the lemon mixture, use a gentle folding motion. This helps keep the mousse light and fluffy.
- Garnishing too early: Wait until just before serving to add any garnishes like whipped cream or lemon slices, as they may lose texture if prepared too soon.
