Two-thirds of a cup of dry macaroni becomes 1 cup of macaroni after being cooked. Two-thirds of a cup of dry macaroni is enough pasta for a single 2-ounce serving.
Macaroni should take about 9 to 10 minutes to cook. To cook dry macaroni, bring a pot of water to a rolling boil. Use 1 quart of water for each 1/4 pound of pasta. Add a couple teaspoons of salt to the water for flavor. Add the macaroni to the boiling water. Keep stirring the pasta to ensure that pieces don't stick to the bottom of the pot. The macaroni is done when there is no longer a whitish area of uncooked pasta in the inside.
