In a blender, process the corn kernels with the cilantro leaves and water. If necessary, add the Half & Half. You should get a smooth texture.
Transfer the mixture to a bowl, add eggs, salt, pepper, and sugar, and stir to combine.
Grease the bottom and sides of an 8" x 8" pyrex or baking pan. Pour half the corn mixture in the pyrex, add the grated queso fresco, and cover with the remaining corn.
Sprinkle with Parmesan cheese.
Bake for 1 hour.
Serve with salsa criolla.
