Gradually pour in the milk while whisking to prevent lumps. Let simmer for 3 minutes. Reduce heat to medium, add salt and paprika, and continue mixing. Incorporate shredded mozzarella cheese, one handful at a time, stirring each addition until melted and smooth. Pour in heavy cream, mix thoroughly, and let the sauce bubble gently for 2 more minutes.
