Prior to my high cholesterol diagnosis, I enjoyed making Italian sausage gnocchi with a parmigiano reggiano butter cream sauce. Unfortunately, I've forgotten how to make the sauce. I remember using butter, cornstarch or flour (can't remember which), cream, and cheese. Does any food 52er know how to make this type of cheese sauce. My son requested this for his birthday dinner tomorrow night so I'd like it to turn out as he remembered from his childhood. Thank you!
