Packaging says to cook pasta in a lot of water, but this is because that is what large kitchens do, as they reuse the water throughout the day.
In the home kitchen you get closer to the reused, starchy water, by simply using less water and stirring.
I've lived in Italy for most of my life and I have never seen a pasta street vendor. Pasta is something that you eat sitting down.
Especially if you crumble in some extra parmigiano reggiano.
Highly recommend you try it at least once.
I use zero salt. IME it's unnecessary.
You need a little experimentation to figure out how much water you need, then you'll have perfectly cooked pasta when the sauce is appropriately reduced.
I'm saying that yes, you can have a good pasta dish without salt, not that it doesn't taste better with salt.
1. If you don't salt enough, no matter how good you make the sauce, or how fancy the noodle is, you're not going to have a good pasta dish. This seems to be one of the primary positions of this paper (although I didn't read it)
2. It's commonly known that Italian street vendors serving pasta would re-use the water throughout the day. This led to an increasing amount of starch being extracted into the water and ultimately, a better noodle closer to the end of the day. Starch is important and this is why pasta water is key to the finish of a pasta dish.
