Instructions:
- Prepare the lemon custard:
- In a medium saucepan, whisk together the egg yolks, granulated sugar, cornstarch, and a pinch of salt.
- Gradually whisk in the cold water and lemon juice.
- Cook the mixture over medium heat, stirring constantly until it thickens and starts to bubble (about 5 minutes).
- Once thickened, remove from heat and stir in the lemon zest and vanilla extract (optional). Let it cool to room temperature.
- Whip the cream:
- In a separate mixing bowl, beat the heavy whipping cream with powdered sugar using a hand mixer until stiff peaks form.
- Combine the custard and whipped cream:
- Gently fold the cooled lemon custard into the whipped cream until well combined. Be careful not to deflate the whipped cream too much.
- Chill the mousse:
- Spoon the lemon mousse into serving bowls or glasses and refrigerate for at least 2 hours, or until set.
- Serve:
- Once chilled, top with a dollop of whipped cream and garnish with lemon slices.
Enjoy your light and fluffy Lemon Mousse, a perfect balance of tart and sweet!
