Sift flour into a large cooking pot.

Remove dough from saucepan and allow to cool before use.
I have seen other variations of this.

The technique is the same but the quantities vary.
Some recipes say that it is important to stir the recipe consistently while it cooks. Others say using boiled water improves the texture and some suggest that boiled water is so effective that if you use it you dont really need to cook at all (just stir in a bowl until it has cooled considerably.
