Warm lime juice gently, then stir in gelatin until dissolved. Cool slightly.
Whip heavy cream and powdered sugar until soft peaks form.
Fold in lime zest and cooled gelatin-lime mixture until light and airy.

✨ Tips
For an even fresher taste, add a touch of mint to the mousse.
Make it tropical by swapping part of the lime juice with coconut milk.
