I used to make this fairly often for my husband many moons ago, when we were both skinny. Also my Dad, man he loved it! I'm making it tonight as a special V-day treat, using fresh fetticine. In the old days, I had always used Ronzoni Fetticine (that's all you could get) and I used their recipe on the back of the box. I remember egg yolks, but when I google recipes now I only see cream, butter and parmesan. Is my memory going too? Or maybe now everyone's afraid of raw eggs? Just curious, I'll probably throw one in for old times sake.
