When the raviolis are ready, you can cook some of them and put the rest in the freezer. It will stay there good at least for a week. In order to cook, boil the water in a deep pot, and cook raviolis in rolling boiling water for 10 minutes. They are done! I like to fry them after cooking, adding a teaspoon of butter, to have a little bit of crust. I believe it tastes better that way. And you can experiment with different toppings on the side of your choice: ketchup, sour cream, mayo, mustard, or anything you like.
