User: Please, give me a short bullet list of main ingredients and procedure in order to cook risotto.
Assistant: Risotto can be cooked with different recipes and ingredients, however the cooking procedure is standard and the basic ingredients are common in all recipes.

- First of all rice is briefly cooked in a soffritto made with onions and butter but also olive oil can be used
- This first phase is called tostatura and it’s important because it coats each rice grain with a film of fat
- Then you need to add white wine until is absorbed by the grains
- Raise then the heat to medium-high
- Now you need to start adding boiling stock in small amounts while constantly stirring
- When the rice is cooked take off the pot from the heat and vigorously beating in refrigerated balls of Parmesan cheese and butter
