Ingredients
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
- 3 large whole eggs
- 3 large egg yolks
- 1 cup plus 2 tablespoons granulated sugar
- 2 teaspoons lemon zest
- 1/2 cup freshly squeezed lemon juice, about 4 lemons
- Pinch of salt
For the Whipped Cream Layer

- 1/2 cup homemade lemon curd, room temperature (from above)
- 1 cup heavy whipping cream, cold
- 1/3 cup powdered sugar
- 1/2 teaspoon pure vanilla extract

How to Make Fresh Lemon Mousse
Step 1: Prepare the Lemons
Zest the lemons carefully, removing only the yellow part. Cut them in half and juice them to reserve 1/2 cup of lemon juice.
Step 2: Make the Lemon Curd
In a large mixing bowl, cream together the unsalted butter until fluffy. Gradually add granulated sugar, salt, and lemon zest. Mix well until combined.
Step 3: Add Eggs and Cook Mixture
Crack the eggs into a small bowl and remove any chalaza. Add eggs one at a time to the mixing bowl while mixing well after each addition. Pour in reserved lemon juice and mix thoroughly.
Step 4: Thicken on Stove
Transfer this mixture to a medium saucepan. Cook over low heat while stirring constantly until it thickens (about 8–10 minutes). Remove from heat.
Step 5: Cool the Curd
Spoon the lemon curd into another bowl. Let it cool to room temperature while covering with plastic wrap to avoid skin forming on top.
Step 6: Prepare Lemon Filling Base
In a heatproof bowl, combine whole eggs, egg yolks, sugar, zest, juice, and salt. Whisk together before placing over simmering water. Constantly whisk for about 12 minutes until thickened like pudding. Remove from heat and cool for 15 minutes before refrigerating.
Step 7: Whip Egg Whites
Add about two-thirds of the egg whites along with a pinch of salt into your stand mixer bowl. Beat on high speed until soft peaks form then gradually add sugar until stiff peaks form.
Step 8: Combine Mixtures
Carefully fold egg whites into chilled lemon filling using a rubber spatula until fully incorporated.
Step 9: Whip Cream
In the same mixing bowl (no need to wash), beat cold heavy whipping cream on medium-low speed until slightly thickened before increasing speed to high until stiff peaks form.
Step 10: Fold in Cream
Gently fold whipped cream into the lemon mixture followed by adding cooled lemon curd until combined.
Step 11: Chill Mousse
Transfer this mixture into your soufflé dish or individual cups and chill for at least one hour before serving.
Step 12: Prepare Garnish
Once chilled, beat more heavy whipping cream with powdered sugar and vanilla extract until stiff peaks form for topping your mousse.
Step 13: Serve
Pipe dollops of whipped cream on top before serving cold. Optionally place small quarter slices of lemon between dollops for added garnish.
Enjoy your Fresh Lemon Mousse! Store any leftovers in the refrigerator for up to five days or freeze them for up to three months—but remember not to garnish with whipped cream until you’re ready to serve!

How to Perfect Fresh Lemon Mousse
To achieve the best Fresh Lemon Mousse, follow these essential tips for perfecting your recipe every time.
- Use fresh lemons – Freshly squeezed lemon juice provides the best flavor compared to bottled juice.
- Chill your mixing bowl – Chilling your bowl before whipping cream helps achieve better volume and texture.
- Fold gently – When incorporating whipped cream or egg whites, be gentle to maintain airiness in your mousse.
- Cool completely – Ensure that your lemon filling is completely cool before folding it into other ingredients; this helps maintain its structure.
- Taste as you go – Adjust sweetness or acidity according to your preference during preparation to achieve your desired balance.
- Use quality ingredients – High-quality butter, sugar, and vanilla make a noticeable difference in taste.

Common Mistakes to Avoid
When making Fresh Lemon Mousse, it’s easy to make a few common mistakes that can affect the outcome. Here’s how to avoid them:
- Skipping the Zest: Not adding lemon zest can lead to a bland flavor. Always zest your lemons before juicing. The zest adds essential oils that enhance the mousse’s taste.
- Overcooking the Mixture: Cooking the lemon mixture too long can cause it to curdle. Stir constantly and remove from heat as soon as it thickens.
- Not Chilling Properly: Failing to chill the mousse adequately may result in a runny texture. Make sure to chill for at least one hour before serving.
- Inadequate Folding Techniques: Overmixing when folding in whipped cream or egg whites can deflate your mousse. Use gentle folds to maintain that light, airy consistency.
- Using Cold Ingredients: Using cold ingredients can prevent proper emulsification. Ensure your butter and lemon curd are at room temperature before mixing.
