Fill a large pot with water, more than enough to cover the pasta. For one pound of pasta, use about 5 quarts of water. If you use too little water, you could end up with starchy, gluey pasta.
Bring the water to a rolling boil over high heat, then add about 1 teaspoon of salt per quart of water.
Add the pasta to the boiling water and stir well to keep it from clumping or sticking to the bottom of the pan. Don't add oil, as it can prevent sauces from clinging to the pasta.
Give the pasta a quick stir every few minutes to keep it from sticking together.
Using a slotted spoon, remove a few pieces of pasta to a plate and taste it for doneness. It should still be slightly chewy, neither too soft nor too firm.
Drain the pasta. Avoid rinsing the pasta unless you want to wash off the starch or cool it with cold water, such as for a salad.
