Cooking times vary by pasta type, but here's the trick to perfectly pressure-cooked pasta: look at the suggested cooking time on the package of your pasta, and cut the time in half. If it's an odd number, round down. So, if the package suggests 11 minutes until pasta is cooked to al dente, round down to m10, cut that time in half, and you're setting your pasta to cook for 5 minutes. If the package suggests 15 minutes, you'll pressure cook the pasta for 7 minutes.
