Semifreddo and granita: Jacob Kenedy's recipes for Italian summer desserts
To prepare the tiramisu semifreddo, whisk egg whites and sugar over low heat, then whip until stiff peaks form, and mix the remaining ingredients carefully.
Granita is an ancient Sicilian treat originally made with shaved snow, fruit syrups and citrus... Eventually, they swapped the snow for sweetened water and it became a balanced, icy treat.
