Context: There are many different risotto recipes with different ingredients, but they are all based on rice of an appropriate variety, cooked in a standard procedure. Risotto, unlike other rice dishes, requires constant care and attention. The rice is not to be pre-rinsed, boiled, or drained, as washing would remove much of the starch required for a creamy texture. 
 The rice is first cooked briefly in a soffritto of onion and butter or olive oil to coat each grain in a film of fat, called tostatura; white wine is added and must be absorbed by the grains. When it has been absorbed, the heat is raised to medium-high, and boiling stock is gradually added in small amounts while stirring constantly. The constant stirring, with only a small amount of liquid present, forces the grains to rub against each other and release the starch from the outside of the grains into the surrounding liquid, creating a smooth creamy-textured mass. When the rice is cooked the pot is taken off the heat for mantecatura, vigorously beating in refrigerated balls of grated parmesan cheese and butter, to make the texture as creamy and smooth as possible. It may be removed from the heat a few minutes earlier and left to cook with its residual heat.
Properly cooked risotto is rich and creamy even if no cream is added due to the starch in the grains. It has some resistance or bite (al dente) and separate grains. The traditional texture is fairly fluid, or all'onda ("wavy" or "flowing in waves"). It is served on flat dishes and should easily spread out but not have excess watery liquid around the perimeter. It must be eaten at once, as it continues to cook in its own heat, making the grains absorb all the liquid and become soft and dry


Question: Please, give me a short bullet list of main ingredients and procedure in order to cook risotto.

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
