For the Lemon Curd

- 1 cup granulated sugar
- 1 tablespoon fresh lemon zest
- Dash salt
- 4 large eggs
- 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, ensuring only to remove the yellow zest without touching the white pith. Cut the lemons in half and juice them. Set aside 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 zest; mix well. Crack eggs into a small bowl, removing any Chalaza from each yolk. Add eggs one at a time to the mixing bowl, mixing well after each addition. Add reserved lemon juice and salt; mix until combined.
Step 3: Cook Mixture
Transfer the mixture to a medium saucepan over low heat. Stir constantly until thickened (about 8-10 minutes). Remove from heat once thickened.
Step 4: Cool Curd
Spoon lemon curd into a bowl. Let cool to room temperature, covering with plastic wrap directly on top to prevent skin formation.
Step 5: Prepare Filling Base
In a heatproof bowl, whisk together whole eggs, egg yolks, sugar, lemon zest, lemon juice, and a pinch of salt. Place over simmering water (medium heat) while whisking constantly until thickened (about 12 minutes). Allow cooling for 15 minutes before refrigerating for 1-2 hours.
Step 6: Beat Egg Whites
Add about two-thirds of egg whites along with a pinch of salt to your stand mixer fitted with a whisk attachment. Beat on high until soft peaks form. Gradually add sugar until stiff peaks are achieved. Carefully fold beaten egg whites into chilled lemon filling using a rubber spatula.
Step 7: Whip Cream
Using the same mixing bowl (no need to wash), add cold heavy whipping cream. Beat on medium-low speed until slightly thickened before increasing speed to high until stiff peaks form. Gently fold whipped cream into the lemon mixture.
Step 8: Combine with Curd
Carefully fold room temperature homemade lemon curd into the combined mixture. Transfer everything into your soufflé dish or individual serving cups.
Step 9: Chill Mousse
Chill for at least one hour before serving.
Step 10: Prepare Whipped Topping
For whipped toppings, beat heavy whipping cream with powdered sugar and vanilla extract until stiff peaks form. Pipe dollops onto chilled mousse before serving.
Step 11: Garnish (Optional)
For an extra touch, place small quarter slices of lemon between dollops of whipped cream as garnish.
Step 12: Serve Cold
Serve your Fresh Lemon Mousse cold! Refrigerate leftovers for up to five days or freeze for up to three months without garnishing until thawed.

How to Perfect Fresh Lemon Mousse
Achieving the perfect Fresh Lemon Mousse involves careful preparation and attention to detail. Here are some tips to elevate your mousse-making skills.
Use fresh lemons: Always opt for fresh lemons rather than bottled juice. Freshly squeezed juice delivers the best flavor and aroma.
Chill your mixing bowl: Before whipping cream, chill your mixing bowl in the refrigerator for about 10 minutes. This helps achieve better volume and stability in your whipped cream.
Fold gently: When incorporating egg whites and whipped cream into your lemon mixture, fold gently to maintain airiness. Over-mixing can deflate your mousse.
Check consistency: Ensure that your lemon curd has thickened properly before adding it to the filling. A well-thickened curd enhances the texture of the mousse.
Taste as you go: Adjust sweetness by tasting during preparation. You can always add more sugar or lemon juice according to your preference.
Allow proper chilling time: After assembling, let the mousse chill adequately in the refrigerator. This helps set its texture and melds flavors beautifully.
Best Side Dishes for Fresh Lemon Mousse

Common Mistakes to Avoid
Making Fresh Lemon Mousse can be simple, but there are a few common mistakes to watch out for.
- Bold Zesting Technique: Not properly zesting the lemons can lead to a bitter taste. Be sure to only remove the yellow outer layer and avoid the white pith.
- Bold Egg Handling: Overmixing the eggs can result in a dense mousse. Incorporate them gently and fold carefully to maintain airiness.
- Bold Temperature Control: Adding warm ingredients to cold mixtures can cause separation. Always let your lemon curd cool before folding it into the mousse.
- Bold Cream Whipping: Whipping the cream too much can turn it into butter. Stop whipping when stiff peaks form for a light texture.
- Bold Chilling Time: Skipping the chilling time will affect the mousse’s consistency. Allow it to chill for at least an hour for best results.
