Ingredients
For the Lemon Curd
- 1 stick unsalted butter, room temperature
- 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)
- Salt
For the Whipped Cream
- 1 cup heavy whipping cream
- 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 to remove only the yellow zest without including any white pith. Set aside. Cut the lemons in half and juice them, reserving 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 in the sugar, salt, and lemon zest, mixing well. Crack open all four eggs into a small bowl, removing any chalaza from each yolk. Add eggs one at a time to the mixing bowl while mixing thoroughly after each addition. Then add in reserved lemon juice and salt; mix until combined.
Step 3: Cook Curd Mixture
Transfer this mixture to a medium saucepan over low heat. Stir constantly until it thickens, which should take about 8-10 minutes. Once thickened, remove it from heat.
Step 4: Cool Curd
Spoon your lemon curd into a bowl and let it cool at room temperature. Place plastic wrap directly on top to prevent skin formation as it cools.
Step 5: Create Lemon Filling
In a heatproof bowl, combine three whole eggs, three yolks, one cup of sugar, lemon zest, lemon juice, and a pinch of salt. Whisk together thoroughly. Place over simmering water on medium heat while whisking constantly until it thickens like pudding—about 12 minutes. Remove from heat and cool for about 15 minutes before refrigerating for at least one hour.
Step 6: Prepare Egg Whites
Add about two-thirds of your egg whites along with a pinch of salt into your stand mixer fitted with a whisk attachment (or use a hand mixer). Beat on high until soft peaks form; then add two tablespoons of sugar and continue beating until stiff peaks develop.
Step 7: Combine Mixtures
Using a rubber spatula, gently fold your whipped egg whites into the chilled lemon filling mixture.
Step 8: Whip Cream
In the same mixing bowl (no need to wash), add cold heavy whipping cream. Beat on medium-low speed initially to prevent splatter before increasing speed to high until stiff peaks form. Carefully fold this whipped cream into your existing mixture.
Step 9: Add Lemon Curd
Gently incorporate your room-temperature homemade lemon curd into this blended mixture until evenly mixed.
Step 10: Chill Mousse
Transfer everything into a soufflé dish (7-inch diameter x 3-inch deep) or individual serving bowls. Refrigerate for at least one hour before serving.
Step 11: Finish with Whipped Cream
For decoration, whip additional heavy cream with powdered sugar and vanilla extract until stiff peaks form. Transfer this whipped cream to a decorating bag with your favorite piping tip or simply spoon dollops onto your mousse surface.
Step 12: Serve Cold
Optionally garnish with small quarter slices of fresh lemon between dollops of whipped cream if desired. Serve cold and enjoy! Store leftovers in the refrigerator for up to five days or freeze for up to three months but do not garnish until ready to serve.
Now you’re all set to create an exquisite Fresh Lemon Mousse that will surely be enjoyed by all!
How to Serve Fresh Lemon Mousse
Fresh Lemon Mousse is a delightful dessert that can be served in various ways. Whether you’re hosting a dinner party or enjoying a casual meal, these serving suggestions will elevate your dessert experience.
Individual Serving Cups
- Use small glass cups or ramekins to present individual portions of lemon mousse. This not only looks elegant but also makes serving easy.
Garnished with Fresh Berries
- Top each serving with a mix of fresh berries like strawberries, blueberries, or raspberries. The tartness complements the sweetness of the mousse beautifully.
Whipped Cream Topping
- Pipe dollops of freshly whipped cream on top for added richness. A sprinkle of lemon zest on the cream enhances the citrus flavor.
Lemon Slices Decoration
- Add thin slices of lemon as a garnish around the mousse. This adds a pop of color and an extra hint of freshness.
Served with Shortbread Cookies
- Accompany your mousse with buttery shortbread cookies. Their crunch provides a nice contrast to the creamy texture of the mousse.
Layered Dessert
- Create layers by alternating lemon mousse and crushed graham crackers in a glass dish. This adds an interesting texture and makes for an eye-catching presentation.
How to Perfect Fresh Lemon Mousse
To achieve the perfect Fresh Lemon Mousse, pay attention to detail during preparation. Here are some helpful tips:
-
Use room temperature ingredients: Room temperature eggs and butter blend more smoothly, resulting in a creamier mousse.
-
Whip egg whites properly: Ensure that your egg whites are beaten until stiff peaks form for light and airy texture.
-
Fold gently: When incorporating whipped cream or egg whites into the lemon mixture, fold gently to maintain airiness.
-
Chill adequately: Allow the mousse to chill for at least one hour before serving to achieve the right consistency and flavor.
-
Taste as you go: Adjust sweetness or tartness by tasting at different stages; this ensures that it meets your preference perfectly.
Best Side Dishes for Fresh Lemon Mousse
Fresh Lemon Mousse pairs well with various side dishes that enhance its flavors. Here are some delightful options:
- Fruit Salad: A refreshing mix of seasonal fruits provides a light contrast to the richness of the mousse.
- Vanilla Ice Cream: The creamy sweetness of vanilla ice cream complements the tartness of lemon perfectly.
- Pavlova: A crisp meringue base topped with fresh fruit brings additional textures and flavors that pair well with lemon.
- Chocolate Biscotti: The crunch and chocolate flavor add depth when enjoyed alongside lemon mousse.
- Almond Cake: A moist almond cake provides a nutty backdrop that balances out the citrus notes in the mousse.
- Coconut Macaroons: These chewy treats not only taste great but also offer a tropical twist that pairs nicely with lemons.
- Cheese Platter: Include soft cheeses like mascarpone or ricotta for a savory element that contrasts beautifully with sweet desserts.
- Lemon Sorbet: For those who love citrus, serve lemon sorbet as a refreshing palate cleanser before indulging in the mousse.
Common Mistakes to Avoid
When making Fresh Lemon Mousse, it’s easy to make mistakes that can affect the outcome. Here are some common pitfalls and how to avoid them.
- Overmixing the Egg Whites: Overmixing can lead to a dry texture. Beat until soft or stiff peaks form, but stop once you reach the desired consistency.
- Ignoring Temperature: Using cold ingredients can hinder the emulsification process. Make sure your butter and eggs are at room temperature for a smooth mixture.
- Not Chilling Properly: Skipping the chilling step can result in a runny mousse. Allow it to set in the refrigerator for at least an hour before serving.
- Using Bottled Lemon Juice: Bottled lemon juice lacks the fresh taste of real lemons. Always opt for freshly squeezed lemon juice for the best flavor.
- Inadequate Folding Technique: Folding too aggressively can deflate your mousse. Use gentle movements to maintain its airy texture when combining ingredients.
