How to Make Fresh Lemon Mousse
Creating this luscious mousse involves several steps, but each one is straightforward. Follow along to achieve your delicious dessert!
Step 1: Prepare Your Lemons
- Zest the lemons carefully, avoiding the white pith. Set aside.
- Cut lemons in half and juice them to reserve 1/2 cup of fresh lemon juice.
Step 2: Make the Lemon Curd
- In a large mixing bowl, cream together the butter, sugar, salt, and lemon zest until well combined.
- Crack eggs into a small bowl; remove any chalaza before adding them one by one to the mixing bowl while mixing well after each addition.
- Pour in lemon juice and mix until combined.
- Transfer this mixture to a medium saucepan over low heat.
- Stir constantly until it thickens (about 8-10 minutes), then remove from heat.
Step 3: Cool the Curd
- Spoon your lemon curd into a bowl to cool at room temperature.
- Cover with plastic wrap directly on top to prevent skin formation while cooling completely.
Step 4: Create the Lemon Filling
- In a heatproof bowl, combine whole eggs, egg yolks, sugar, zest, lemon juice, and salt; whisk well.
- Place over simmering water (double boiler) while constantly whisking until thickened like pudding (around 12 minutes).
- Remove from heat; allow cooling for about 15 minutes before refrigerating for at least one hour.
Step 5: Whip Egg Whites
- In a stand mixer with whisk attachment (or using hand mixer), add about two-thirds of egg whites and salt; beat until soft peaks form.
- Gradually add sugar while beating until stiff peaks form.
Step 6: Fold in Mixtures
- Use a rubber spatula to fold beaten egg whites into chilled lemon filling gently.
- In another clean mixing bowl, whip heavy cream until stiff peaks form; fold this into your lemon mixture as well.
Step 7: Combine with Lemon Curd
Gently fold in cooled homemade lemon curd into your airy mixture until just combined.

Common Mistakes to Avoid
When making Fresh Lemon Mousse, avoiding common pitfalls can enhance your results. Here are some mistakes to watch out for:
- Boldly mixing ingredients too quickly: This can create uneven textures. Take the time to mix gently and thoroughly for a smooth mousse.
- Overcooking the lemon curd: Cooking it too long will make it grainy. Keep a close eye and stir constantly until it thickens, about 8-10 minutes.
- Skipping the chilling step: Not allowing the mousse to chill properly can lead to a runny texture. Let it cool in the fridge for at least one hour before serving.
- Not folding egg whites carefully: Overmixing can deflate your mousse. Fold gently to maintain airiness for that fluffy texture.
