Salt your water
The first moveNot a pinch. Not a tablespoon. A handful — enough that the water tastes like a mild broth when you dip your finger in.
The rule I go by: pasta can't be seasoned from the outside after the fact. The salt has to get inside while it's cooking. So I add it when the water boils, stand back from the steam, and taste it before the pasta goes in. If it doesn't make me blink a little, I add more. This is the single technique that made the biggest difference in my cooking. Everything else is secondary. See how this applies in the finishing section below.
