It requires flour, that's all.
Basically make dough (Flour and Water, that's all you need though I like to add egg for that additional 'yellow' color and for flavour) and continue to kneed it till it becomes mold-able.
Kneed the dough into long strands, as thin or thick as you like but ensuring they're atleast a bit thick.
Bring a pot (large) to a boil and watch them absorb that stuff.
Either eat once they turn a yellow or atleast a deeper tan colour.
If you want you can then take them out and fry them in oil which is nice.
