Fresh Lemon Mousse Ingredients

For the Lemon Curd
Unsalted Butter (1 stick) – Adds richness to the lemon curd; if unavailable, salted butter can be used but adjust the added salt.
Granulated Sugar (2 cups total) – Sweetens both the curd and mousse while balancing tartness perfectly.
Fresh Lemon Zest (1 tablespoon + 2 teaspoons) – Enhances the lemon flavor; avoid dried zest as it lacks the same aroma.
Salt (a dash) – Elevates sweetness, enhancing the overall flavor profile.
Large Eggs (4 whole + 3 yolks) – Creates a creamy consistency and provides structure; use pasteurized eggs if concerned about raw consumption.
Fresh Lemon Juice (1 cup) – The star of the dish, offering the main tartness; about 8 lemons should suffice.

For the Mousse
Heavy Whipping Cream (2 cups total, divided) – Adds a lightness that makes the mousse airy; ensure it’s cold for proper whipping.
Powdered Sugar (1/3 cup) – Sweeter than granulated sugar, perfect for achieving a light finish in the whipped cream.
Pure Vanilla Extract (1/2 teaspoon) – Introduces depth of flavor in the whipped cream that complements the lemon well.

Keep these Fresh Lemon Mousse ingredients handy, and get ready for a dessert that’s sure to brighten everyone’s day!

Step‑by‑Step Instructions for Fresh Lemon Mousse

Step 1: Make the Lemon Curd
Begin by zesting and juicing the fresh lemons until you have about 1 cup of juice. In a medium saucepan over low heat, cream together 1 stick of unsalted butter, 1 cup of granulated sugar, and the lemon zest. Gradually add in 4 whole eggs and 3 egg yolks, whisking continuously. Pour in the lemon juice and cook, stirring constantly for about 8 minutes, or until the mixture thickens and coats the back of a spoon. Remove from heat, cool slightly, and then refrigerate until set.

Step 2: Prepare the Lemon Filling
In a heatproof bowl, combine 4 whole eggs, 3 egg yolks, 1 cup of granulated sugar, 1 tablespoon of lemon zest, 1 cup of fresh lemon juice, and a dash of salt. Place the bowl over a saucepan with simmering water, creating a double boiler setup. Whisk constantly for approximately 12 minutes, ensuring the mixture thickens to a custard-like consistency. Once thickened, take it off the heat, let cool, and then place it in the refrigerator.

Step 3: Whip Egg Whites
In a clean mixing bowl, beat 3 egg whites with a pinch of salt using an electric mixer until soft peaks begin to form. Gradually add in 1 cup of granulated sugar while continuing to beat the mixture. Keep whipping until you achieve stiff peaks that hold their shape without collapsing. This step is crucial for the airy texture of the Fresh Lemon Mousse, so take your time to get those peaks right.

Step 4: Combine Mixtures
Once the lemon filling has cooled, take it out of the fridge. Gently fold in the whipped egg whites into the lemon filling using a spatula, being careful not to deflate the mixture. After thoroughly combining, gently fold in the chilled lemon curd to ensure an even distribution of flavors. Transfer the combined mixture into your serving dishes or a large bowl and refrigerate it until fully set, about 2-3 hours.

Step 5: Make Whipped Cream
To prepare the delightful topping, pour 2 cups of cold heavy whipping cream into a mixing bowl. Add in 1/3 cup of powdered sugar and 1/2 teaspoon of pure vanilla extract. Whip on medium-high speed until soft peaks form, and the cream is light and airy. Once your Fresh Lemon Mousse has set, dollop the whipped cream generously on top, and feel free to garnish with additional lemon zest or fresh berries for a colorful finish.

Expert Tips for Fresh Lemon Mousse

  • Egg Whites Room Temperature: Use room temperature egg whites for optimal whipping, ensuring they reach the desired fluffy consistency.

  • Avoid Over-Whipping: Be cautious when whipping cream; it’s best to stop once soft peaks form to prevent a grainy texture in your Fresh Lemon Mousse.

  • Chill Your Equipment: For the lightest whipped cream, chill your mixing bowl and beaters beforehand to help achieve that perfect airy finish.

  • Make Ahead Option: For convenience, prepare the lemon curd a day in advance. This not only saves time but also enhances the flavors as it rests.

  • Check for Stiff Peaks: When whipping egg whites, look for stiff peaks that hold their shape. This is key for achieving the mousse’s delightful texture.

Fresh Lemon Mousse Recipe FAQs

How do I choose ripe lemons for Fresh Lemon Mousse?
Absolutely! Look for lemons that are bright yellow and feel heavy for their size. Avoid any with dark spots all over or a dull appearance, as these may be overripe.

What is the best way to store Fresh Lemon Mousse?
You can store your Fresh Lemon Mousse in an airtight container in the refrigerator for up to 3 days. To keep it fresh, seal it well and place it on a shelf rather than in the door, where temperatures can fluctuate.

Can I freeze Fresh Lemon Mousse for later?
Yes, you can freeze Fresh Lemon Mousse for up to 1 month! To do so, scoop the mousse into an airtight container, ensuring there’s no excess air inside. When ready to enjoy, transfer it to the fridge to thaw overnight. Please note that the texture may slightly change after freezing.

What should I do if my mousse doesn’t set properly?
If your mousse hasn’t set well, it might be due to under-whipping the egg whites or the lemon filling mixture. Make sure to whip the egg whites until stiff peaks form, and ensure the filling is cooked long enough to thicken (around 12 minutes over simmering water should do). If it still doesn’t set, try placing it back in the refrigerator for a longer period.

Is Fresh Lemon Mousse safe for people with egg allergies?
Unfortunately, Fresh Lemon Mousse contains raw and cooked eggs, making it unsuitable for anyone with egg allergies. However, you could look into egg substitute formulas suitable for soufflés or mousse to create a modified, egg-free version.

Can I use store-bought lemon curd instead of homemade?
Certainly! Using store-bought lemon curd can save you time while still delivering a delicious flavor. Just make sure to choose a high-quality product for the best results in your Fresh Lemon Mousse.
