Instructions
Wash lemons thoroughly. Zest the yellow skin finely, then squeeze the juice. Keep zest and juice separate.
Bloom gelatin in water for 5 minutes, then melt until liquid (do not boil!). Stir in the lemon juice and half the zest.
Whip the ice-cold heavy cream with powdered sugar and a pinch of salt until stiff peaks form.
Pour the lukewarm lemon gelatin mixture in a thin stream into the whipped cream while whisking continuously but gently.
Place sponge layer in the pan. If dry, brush with a little sugar syrup or Limoncello. Pour the mousse over it.
Smooth the top and refrigerate for at least 4 hours.
To serve, wrap a hot towel around the pan for a few seconds to release. Garnish with remaining zest and lemon slices.
