- 1 tablespoon fresh lemon zest
- Dash salt
- 4 large eggs
- 1/2 cup freshly squeezed lemon juice, about 4 lemons

For the Whipped Cream

- 1/3 cup powdered sugar

How to Make Fresh Lemon Mousse
Step 1: Prepare Your Lemons
Zest the lemons carefully to remove only the yellow part of the skin. Cut them in half and juice them until you have 1/2 cup of fresh lemon juice.
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 until well combined.
- Crack eggs into a separate bowl; add them one at a time to the butter mixture, mixing well after each addition.
- Stir in lemon juice and salt; combine thoroughly.
- Transfer this mixture to a medium saucepan and cook on low heat while stirring constantly until thickened (about 8-10 minutes). Remove from heat.
Step 3: Cool Curd Mixture
Spoon the warm lemon curd into another bowl to cool. Cover it with plastic wrap directly on top to prevent skin formation. Allow it to cool to room temperature before using.
Step 4: Prepare Lemon Filling
In a large heatproof bowl:
1. Combine whole eggs, egg yolks, sugar, lemon zest, lemon juice, and a pinch of salt.
2. Place over simmering water (double boiler) while whisking continuously until thickened like pudding (around 12 minutes).
3. Once thickened, remove from heat and cool for about 15 minutes before covering with plastic wrap directly on its surface. Refrigerate until chilled (1-2 hours).
Step 5: Whip Egg Whites
Using a stand mixer fitted with a whisk attachment:
1. Add about 2/3 of egg whites with a pinch of salt.
2. Beat on high speed until soft peaks form; add sugar gradually until stiff peaks form.
3. Carefully fold these beaten egg whites into your chilled lemon filling using a rubber spatula.
Step 6: Whip Cream
In the same mixing bowl:
1. Beat heavy whipping cream on medium-low speed until it starts to thicken slightly.
2. Increase speed to high until stiff peaks form; fold this whipped cream into your lemon mixture gently.
Step 7: Combine & Chill
Fold in cooled homemade lemon curd delicately into your mousse mixture. Pour everything into a soufflé dish (7-inch diameter x 3-inch deep) and chill for at least one hour.
Step 8: Finish with Whipped Topping
Once chilled:
1. Beat additional heavy whipping cream with powdered sugar and vanilla until stiff peaks are reached.
2. Pipe or spoon dollops onto the surface of your mousse; optionally garnish with small quarter slices of lemon.
Step 9: Serve Cold
Enjoy your Fresh Lemon Mousse cold! Store leftovers in the fridge for up to five days or freeze for up to three months without garnishing until ready to serve again.
This delightful dessert is sure to become a favorite among friends and family!

Common Mistakes to Avoid
Making Fresh Lemon Mousse can be a delightful experience, but certain pitfalls may hinder your success. Here are some common mistakes to watch out for:
- Using cold ingredients: Always ensure your eggs and cream are at room temperature before starting. Cold ingredients can prevent proper mixing and aeration.
- Overcooking the lemon curd: Cook the lemon curd just until it thickens. Cooking it too long can lead to a grainy texture, ruining the smoothness of your mousse.
- Skipping the chilling step: It’s essential to refrigerate the mixture thoroughly before serving. This allows it to set properly and enhances flavors.
- Not folding gently: When combining whipped cream and egg whites into the lemon filling, fold gently to maintain airiness. Overmixing can deflate your mousse.
- Ignoring ingredient quality: Use fresh lemons and high-quality butter for the best flavor. Subpar ingredients can lead to a lackluster mousse.
