Ingredients
- 3 large eggs, separated
- 2/3 cup granulated sugar, divided
- 1 tablespoon finely grated lemon zest (from about 2 lemons)
- 1/3 cup freshly squeezed lemon juice (from about 2-3 lemons)
- 1/8 teaspoon salt
- 1 cup heavy whipping cream, cold
- 1/2 teaspoon pure vanilla extract (gluten free)
- Optional: extra lemon zest or thin lemon slices, for garnish
- Optional: fresh berries (like raspberries or blueberries), for serving
Instructions
- Prepare the lemon base: In a medium heatproof bowl, whisk together the egg yolks, 1/3 cup of the sugar, lemon zest, and lemon juice. Place the bowl over (not in) a pot of gently simmering water to create a double boiler. Whisk constantly until the mixture thickens and reaches 170°F (about 6–8 minutes). Remove from heat and let cool to room temperature, stirring occasionally to prevent a skin from forming.
- Whip the egg whites: In a clean mixing bowl, beat the egg whites and salt using a hand mixer or stand mixer on medium-high speed until soft peaks form. Gradually add the remaining 1/3 cup sugar and continue beating until stiff, glossy peaks form.
- Whip the cream: In a separate chilled bowl, beat the cold heavy cream and vanilla extract until medium peaks form (it should hold its shape but still look soft and creamy).
- Combine: Gently fold the cooled lemon mixture into the whipped cream using a spatula. Next, fold in the beaten egg whites in two additions, being careful not to deflate the mixture. Fold until just combined—do not overmix.
- Chill: Spoon or pipe the mousse into individual serving glasses or bowls. Cover and refrigerate for at least 3 hours, or until set and thoroughly chilled.
- Serve: Garnish with extra lemon zest, thin lemon slices, or fresh berries if desired. Serve cold and enjoy!
Tips
- Egg safety: This recipe uses raw egg whites. For maximum safety, use pasteurized eggs, which are available in most supermarkets. Alternatively, you can use powdered egg whites prepared per package instructions.
- Make it dairy free: Substitute the heavy cream with a dairy free alternative such as coconut cream (use the thick part from a chilled can) for a lactose-free and dairy-free option. Note that this will impart a mild coconut flavor.
- Lemon juice: Always use freshly squeezed lemon juice for the best flavor. Bottled lemon juice can taste flat and lacks the bright, aromatic zest.
- Don’t overmix: When folding the whipped cream and egg whites into the lemon base, use a gentle hand. Overmixing can knock out the air, resulting in a dense mousse.
Serving Suggestions
- As a parfait: Layer the mousse with fresh berries and gluten free cookie crumbles for a beautiful parfait.
- With shortbread: Serve with gluten free shortbread or crisp gluten free wafers for added texture.
- In tart shells: Spoon the mousse into pre-baked gluten free tart shells for a handheld dessert perfect for parties.
- Straight up: Simply serve in elegant glasses with a twist of lemon zest and a sprig of mint for a minimalist, refreshing presentation.
Variations
- Lime mousse: Swap the lemon zest and juice for lime for a tarter, tropical twist.
- Lemon-berry swirl: Gently fold in a few spoonfuls of berry puree (such as raspberry or blueberry) for a vibrant swirl and added fruitiness.
- Honey lemon mousse: Replace half the sugar with mild honey for a floral, nuanced sweetness that pairs beautifully with lemon.
- Lemon-lavender mousse: Infuse the cream with a teaspoon of culinary lavender buds (then strain) before whipping for an aromatic, floral note.
Storage and Reheating
Lemon mousse should be stored in the refrigerator, covered, for up to 3 days. Because it contains whipped cream and eggs, do not leave it at room temperature for more than 2 hours. The texture is at its best within the first 24 hours, but it will remain light and flavorful for up to 3 days. This dessert is not suitable for freezing, as freezing will cause the mousse to separate and lose its airy texture. There is no need to reheat lemon mousse, as it is served chilled—simply remove from the refrigerator just before serving.
Frequently Asked Questions
- Can I make this lemon mousse ahead of time?
- Yes! Lemon mousse is an excellent make-ahead dessert. Prepare it up to 24 hours in advance for the best texture and flavor. Store it covered in the refrigerator until ready to serve. Just garnish before serving for the freshest look.
- What can I use instead of raw egg whites?
- If you are concerned about consuming raw egg whites, you can use pasteurized egg whites (sold in cartons) or reconstituted powdered egg whites, following package directions. Some recipes substitute whipped aquafaba (the liquid from canned chickpeas) for a vegan alternative, though the texture and flavor will differ slightly.
- Is this lemon mousse safe for people with celiac disease?
- Yes, this recipe contains no gluten ingredients. However, always double-check that your vanilla extract and any garnishes (like cookies or wafers) are certified gluten free to avoid any cross-contamination. If serving to someone with celiac disease, ensure all utensils and bowls are thoroughly cleaned and that no gluten-containing foods are prepared nearby.
- Can I use bottled lemon juice instead of fresh?
- While you can use bottled lemon juice in a pinch, the flavor will not be as bright or fresh. Freshly squeezed lemon juice and zest are strongly recommended for the best-tasting mousse.
- Why is my mousse runny or not setting?
- If your mousse is runny, it may be due to under-whipped cream or egg whites, or the lemon base may not have thickened enough during cooking. Be sure to beat the egg whites and cream until they hold peaks, and cook the lemon mixture until it visibly thickens. Chill the mousse for at least 3 hours to allow it to set fully.
- Can I double this recipe for a larger group?
- Absolutely! This recipe doubles well. Use a large mixing bowl for folding the ingredients, and ensure the lemon base is completely cooled before combining with the whipped elements. Chill in individual glasses or a large serving bowl, then spoon into cups before serving.
