Mix eggs and sugar together to make semifredo. Place in a steam bath and stir until sugar dissolves. Grate the cheese and mix in the cooked mass, add vanilla, lemon zest, lemon juice and a little salt. Separate the cream separately and mix with other ingredients. Semifredo is ready, now it needs to be distributed and frozen in its forms (preferably freezing for 3-4 hours, although 1 hour is enough).
