How to Make Fresh Lemon Mousse
Step 1: Prepare Your Lemons
Zest the lemons carefully to avoid the white pith. Cut them in half and juice them; reserve 1/2 cup of lemon juice for later use.
Step 2: Make Lemon Curd
Cream the butter using a stand mixer or hand mixer until fluffy. Add sugar, salt, and lemon zest. Mix well. Add eggs one at a time while mixing. Combine with reserved lemon juice. Transfer to a saucepan over low heat. Stir constantly until thickened (about 8–10 minutes). Remove from heat.
Step 3: Cool the Curd
Spoon the lemon curd into a bowl to cool at room temperature. Cover with plastic wrap directly on top to prevent skin formation.
Step 4: Prepare Lemon Filling
In a heatproof bowl, whisk together whole eggs, egg yolks, sugar, lemon zest, lemon juice, and salt. Place over simmering water while whisking constantly until thickened (about 12 minutes). Cool for 15 minutes before refrigerating for 1–2 hours.
Step 5: Whip Egg Whites
Beat about two-thirds of egg whites with a pinch of salt in a stand mixer until soft peaks form. Gradually add sugar until stiff peaks form. Gently fold into cooled lemon filling.
Step 6: Whip Cream
In the same mixing bowl (no need to wash), beat cold heavy cream until slightly thickened. Increase speed until stiff peaks form. Fold whipped cream into the lemon mixture carefully.
Step 7: Combine Mixtures
Gently fold in room-temperature lemon curd into the combined mixtures until just incorporated.
Step 8: Chill
Transfer mixture into souffle dish or serving cups. Chill for at least one hour before serving.
Step 9: Prepare Whipped Cream Topping
Beat cold heavy whipping cream with powdered sugar and vanilla until stiff peaks form. Pipe onto chilled mousse as desired.
Step 10: Serve
Optional garnish with small quarter slices of lemon between dollops of whipped cream if you wish! Serve cold and enjoy your delightful Fresh Lemon Mousse!

How to Perfect Fresh Lemon Mousse
To ensure your Fresh Lemon Mousse turns out perfectly every time, consider these helpful tips.
- Use Fresh Ingredients: Always opt for fresh lemons and high-quality cream to achieve the best flavor and texture.
- Separate Eggs Carefully: Be cautious when separating egg yolks from whites, as any yolk in the whites can prevent them from whipping properly.
- Avoid Overmixing: When folding in whipped cream or egg whites, be gentle to maintain airiness in the mousse.
- Chill Properly: Allow sufficient chilling time. The mousse should set well in the fridge for at least one hour before serving.
- Taste as You Go: Adjust sweetness by tasting your mixture before it sets. You can always add more sugar if needed.
- Experiment with Flavors: Feel free to add other flavors like vanilla or almond extract for a unique twist on your mousse.

Common Mistakes to Avoid
Making Fresh Lemon Mousse can be a delightful experience, but there are a few common pitfalls to watch for.
- Boldly measuring ingredients: Always use accurate measurements for your ingredients. Too much or too little lemon juice or sugar can affect the mousse’s texture and flavor.
- Ignoring egg temperature: Make sure your eggs are at room temperature before using them. Cold eggs do not whip as well, which can result in a dense mousse.
- Skipping the cooling step: Allow your lemon filling and curd to cool completely before combining. This helps create a smooth and airy mousse.
- Overwhipping cream: When whipping cream, stop as soon as stiff peaks form. Overwhipped cream can turn grainy and ruin the texture of your mousse.
- Not folding gently: Be gentle when folding ingredients together. Aggressive mixing will deflate the air bubbles that give the mousse its light and fluffy texture.
