Pistoccus

Preheat your oven to 180°C (350°F). Line two baking sheets with parchment paper.

In a large, very clean bowl, combine the egg whites and salt. Whip with an electric mixer on high speed until stiff peaks form. Set aside.

In a separate bowl, combine the egg yolks, granulated sugar, and lemon zest. Beat with an electric mixer on high speed until the mixture is pale yellow, thick, and fluffy, about 3-5 minutes.
