How to cook a couscous ? Put it in water or put water on it ?

Hi,
How do I have to cook a couscous ? Should I put it in boiling water or put a boiling water on it ?

It is recommended to pour a boiling water over couscous.

The ratio of water to couscous should be 1:1. Per 100 grams of couscous, you should use 100 ml of water.

You can also cook couscous in the water, but you have to be carefull, because it can get easily overcooked.
