In a mixing bowl, whip the cold heavy cream using an electric mixer until soft peaks form.
Gradually add condensed milk while folding gently.
Slowly pour in fresh lemon juice, continuing to fold until smooth and airy.
Spoon the mixture into small serving glasses or ramekins.
Refrigerate for at least 2 hours (or overnight) to set properly.
Sprinkle fresh lemon zest on top for a burst of citrus aroma!
