Like you, I love a good Spaghetti Carbonara. Egg yolks, not cream. But the yolks in carbonara are cooked only until somewhat thickened, not actually cooked. I have a problem with that. I’m just not a big fan of raw, or partially cooked eggs. Also, most of the time, I like cooking enough so there are leftovers, and mainly because of the egg, carbonara is out. It’s really one of those things you cook, and eat, in the moment.
