I will start and steal Mikey's thunder.

This one made things click for me years ago. My copy is now dog-eared and splattered. So many great recipes that I have in frequent rotation. The roast chicken with lemons. Seems pretty boring when you look at it...it is far from it. The best roast chicken unless you're doing on a roti. The Bluefish with potatoes, garlic and olive oil is something we make a couple times a month. It's great with mackerel, unfortunately, the OL is not fond of bluefish or mackerel, so we use monkfish now. The osso buco is on point. The tomato sauce with onions and butter is absolutely ridiculous. Nothing that stupidly easy should be that good, but it is. I have even run across it in restaurants.
There are some misses, though. Her carbonara recipe is an absolute abomination. You would probably get knifed if you tried to serve that in Rome. It was so bad, I never bothered with it again for years until I ran into a proper recipe.
