How much spaghetti should you cook per person?
Spaghetti noodles almost double in size once they are cooked, as do macaroni noodles. However, fresh pasta does not change in size.Use 4 to 6 quarts of water per 1 lb. of uncooked pasta for best results. Kosher salt can be used during the boiling process to enhance the flavor of the pasta.Cooked pasta can be safely stored in the refrigerator for 3 to 5 days. Dry pasta that does not contain egg can be stored for 2 years, and uncooked pasta with egg can be stored for 1 year. Source: thenibble.com
