Question: how many cups of water for 2 cups of pasta?
Answer: Four ounces of tube-shaped pasta like penne, ziti, or corkscrew equals 2 1/2 cups cooked. Four ounces of long-strand pasta like fettuccine, spaghetti, or linguine equals 2 cups cooked. Fill a pot with at least 4 quarts of water for each pound of pasta.
