In a large mixing bowl, combine the heavy cream, confectioner’s sugar, and a pinch of salt.
Using a hand mixer or stand mixer fitted with the whisk attachment, whip on medium speed for about 2–3 minutes until medium peaks form. The whipped cream should hold its shape but still look soft and silky.
Step 2: Fold in Lemon
Gently fold in the lemon curd and lemon zest using a rubber spatula.
Work slowly to keep the whipped cream from deflating too much, ensuring an airy, mousse-like texture.
Step 3: Portion and Chill
Divide the mousse evenly into 8 small dessert glasses, about ½ heaping cup per serving.
Smooth the tops with a spoon or leave them rustic.
Chill in the refrigerator for at least 1 hour, or up to 24 hours, to allow the mousse to set and the flavors to develop.
Step 4: Serve
Just before serving, garnish with a dollop of whipped cream or a sprinkle of fresh lemon zest for a beautiful finishing touch.
Serve chilled and enjoy the creamy, tangy goodness.
