Combine the cheese, sugar, lemon zest and juice, and one egg in a large mixing bowl and mix thoroughly. Add plain bread crumbs just until stiff enough to form into patties.

In a separate bowl, mix additional bread crumbs with cinnamon. In a third bowl, add beaten egg.

Heat 1/4 inch oil in a large pan. Form patties and coat first with the beaten eggs and then with the cinnamon bread crumbs. Fry on both sides until golden brown. Drain on paper towels.
