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

- 2 teaspoons lemon zest
- 1/2 cup freshly squeezed lemon juice, about 4 lemons
- Salt
For the Whipped Cream

- 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: Zest and Juice the Lemons
Start by zesting the lemons carefully to avoid the bitter white pith. Cut them in half and juice them until you have about 1/2 cup of fresh lemon juice.
Step 2: Prepare the Lemon Curd
- In a large mixing bowl, cream the butter until smooth.
- Add sugar, salt, and lemon zest; mix well.
- Crack each egg into a small bowl to remove any chalaza and add them one at a time to the mixture. Mix well after each addition.
- Stir in the lemon juice until combined.
- Transfer this mixture to a medium saucepan over low heat. Continuously stir until it thickens (about 8-10 minutes). Remove from heat.
- Allow the curd to cool to room temperature before covering with plastic wrap directly on top.
Step 3: Make the Lemon Filling
- In a heatproof bowl, combine whole eggs, egg yolks, sugar, lemon zest, lemon juice, and a pinch of salt. Whisk together.
- Place it over simmering water (double boiler) and whisk constantly until thickened like pudding (around 12 minutes).
- Let cool for about 15 minutes before covering with plastic wrap directly on the surface. Refrigerate for 1-2 hours.
Step 4: Fold Egg Whites
- In a stand mixer fitted with a whisk attachment, add about 2/3 of the egg whites along with a pinch of salt.
- Beat on high speed until soft peaks form; then add sugar gradually until stiff peaks form.
- Gently fold these egg whites into your chilled lemon filling using a rubber spatula.
Step 5: Whip Cream
Using the same mixing bowl (no need to clean), add cold heavy whipping cream:
1. Beat on medium-low speed until slightly thickened before turning up to high speed until stiff peaks form.
2. Carefully fold this whipped cream into your lemon mixture using gentle motion.
Step 6: Combine Everything
Gently fold in your room temperature homemade lemon curd into the main mixture until well incorporated.
Step 7: Chill
Transfer everything into a soufflé dish or individual serving cups. Chill in the refrigerator for at least one hour before serving.
Step 8: Final Touches
Before serving:
1. Whip more cream with powdered sugar and vanilla extract until stiff peaks form.
2. Pipe dollops over your mousse or simply spoon it on top as desired.

How to Perfect Fresh Lemon Mousse
To achieve the perfect Fresh Lemon Mousse, follow these tips for a creamy and flavorful dessert.
- Use Room Temperature Ingredients: Ensure butter and eggs are at room temperature for better emulsification, resulting in a smoother texture.
- Fold Gently: When incorporating whipped cream or egg whites, fold gently to maintain airiness; this helps keep your mousse light and fluffy.
- Chill Thoroughly: Allowing the mousse to chill properly will enhance its flavors and improve its texture. Aim for at least one hour in the refrigerator.
- Taste Before Serving: Always taste your mousse before serving to adjust sweetness or acidity if needed. A hint more sugar or lemon juice can elevate the flavors.
- Choose Quality Ingredients: Use fresh lemons and high-quality butter for the best flavor; this makes a significant difference in your final dish.

Common Mistakes to Avoid
When preparing Fresh Lemon Mousse, it’s easy to make a few common mistakes that can affect the final result.
- Overmixing the Ingredients – Mixing too much can lead to a dense mousse instead of the light and airy texture desired. Mix just until combined for best results.
- Ignoring Temperature Requirements – Using ingredients that are not at room temperature can cause the mixture to separate. Ensure all components, like butter and eggs, are at room temperature.
- Skipping Chilling Time – Rushing the chilling process can prevent the mousse from setting properly. Allow ample time in the fridge for perfect consistency.
- Using Bottled Lemon Juice – Fresh lemon juice is key for flavor. Always opt for freshly squeezed juice to enhance the taste of your mousse.
- Not Folding Gently – When incorporating whipped cream or egg whites, folding gently helps retain air, ensuring a fluffy mousse. Be careful not to deflate your mixture.
