Light and Airy Lemon Mousse
Ingredients
- 4 medium lemons (about 1 cup / 240 ml lemon juice)
- 100 g (1/2 cup) granulated sugar
- 150 ml (about 2/3 cup) water
- 40 g (1/3 cup) cornstarch
- Zest of 2 lemons
- 500 ml (2 cups) heavy cream
- 150 ml (2/3 cup) sweetened condensed milk
Step-by-Step Instructions
-
Prepare the Lemon Mixture: In a medium saucepan, combine the juice from the lemons, sugar, water, cornstarch, and lemon zest. Stir well to dissolve the sugar and cornstarch completely.
-
Cook the Mixture: Place the saucepan over medium heat. Continuously stir the mixture until it thickens, about 5–7 minutes. You’ll know it’s ready when it coats the back of a spoon. Avoid boiling, as this can change the texture.
-
Cool Down: Remove the saucepan from the heat and allow the lemon mixture to cool to room temperature—this step is crucial for preventing the whipped cream from melting.
-
Whip the Cream: In a separate large bowl, use a hand mixer or stand mixer to whip the heavy cream until stiff peaks form. This should take about 3–5 minutes. Be careful not to overwhip, or you’ll end up with butter!
-
Combine Mixtures: Gently fold in the condensed milk into the whipped cream until just incorporated. Then, gradually add the cooled lemon mixture, folding gently to maintain the airiness until fully combined.
-
Chill the Mousse: Spoon the mousse into individual serving glasses or bowls. Cover with plastic wrap and chill in the refrigerator for at least 2 hours or overnight for the best results.
Pro Tips
- For a denser mousse: Consider adding an egg yolk to the lemon mixture before cooking, stirring it in after the sugar dissolves.
- Zest perfection: Use a microplane for the lemon zest to get ultra-fine pieces that blend seamlessly into your mousse.
- Taste test: Before chilling, give the mousse a taste! Feel free to adjust sweetness or tartness by adding more sugar or lemon juice if desired.
Common Mistake
- Stirring too vigorously: When folding the lemon mixture into the whipped cream, be gentle. Overmixing will deflate the fluffy texture of the cream.
Tested Note
I found that letting the mousse chill overnight really enhances the flavors and creates a richer taste.
Serving Suggestions
Serve the lemon mousse in clear glass cups or elegant ramekins, garnished with a sprig of mint, fresh berries, or a dusting of powdered sugar for an aesthetic touch.
Storage Instructions
This dessert can be stored in the refrigerator, covered tightly with plastic wrap, for up to 3 days. The texture will remain stable, but it’s best enjoyed fresh.
Reheating Tips
No reheating is required, but if the mousse has been in the fridge for a while, allow it to sit at room temperature for about 10–15 minutes before serving for a creamier texture.
