Directions
-
In a small heatproof bowl, combine 1/3 cup fresh lemon juice and 1 teaspoon lemon zest.

Sprinkle the unflavored gelatin over the lemon mixture and let stand for 10 minutes to soften.

Place the bowl over a saucepan of simmering water (double boiler method) and stir gently until the gelatin is completely dissolved.

Remove from heat and allow the gelatin mixture to cool to room temperature.

In a large chilled bowl, whip the heavy cream until stiff peaks form.

Cover and refrigerate the whipped cream until ready to use.

In a deep, clean bowl, combine egg whites and salt.

Beat the egg whites until soft peaks form.

Gradually add 1 cup of the confectioners' sugar to the egg whites, beating continuously until stiff, glossy peaks form.

In a separate large bowl, beat the room-temperature unsalted butter until soft and fluffy.

Add 1 cup of the confectioners' sugar to the butter and beat until smooth and creamy.

Add the egg yolks one at a time to the butter mixture, beating well after each addition.
-
Alternately add the cooled gelatin mixture and the remaining 1 cup of confectioners' sugar to the butter mixture, beating until smooth and fully incorporated.

Gently fold one-third of the beaten egg whites into the butter mixture to lighten it.

Carefully fold in the remaining egg whites until no white streaks remain.
