Does it matter when you add the salt?
Salt is very soluble in water, and during the cooking process will tend to diffuse within the liquids of the food and permeate inside. Having a salty flavor throughout the food I find tends to help curb salt usage. A good example is pasta, where if you add salt you can achieve a salty taste for the pasta and largely decrease salt you add at the table. My grandmother always said add the salt while you are cooking so you don't have to add twice as much later.
