one easy way to cook ravioli is by boiling it. first, bring 4 quarts (4.5 l) of water for every 1 pound (0.5 kg) of ravioli you're making to a boil. then, add the ravioli to the water and stir to keep the ravioli separated. let the ravioli cook for 4-6 minutes or until they float to the surface of the water.
