Hi Butterfly with all due respect I must say that you are wrong three times:

1- when you say Couscous is Mainly a Moroccan dish. It is found in every single region of Algeria & Tunisia but only in eastern Morocco. A lot of people are under the impression that Couscous is Moroccan only the reason for that is Morocco is a top tourist destination and most North African restaurants outside the region are Moroccan..(We Algerians are less entrepreneurial)

2- Couscous is not heavy on the stomach not as much as pasta or rice.

3-Couscous is never topped with a bland sauce...its either spicy & Hot or Spicy.

I would advise anyone who wants to try it for the first time to not buy the Carrefour already made. The couscous making process is a complicated one and the grain has to be steamed 2 or 3 times.

I will back my arguments up by the fact that I'm a North African Berber (native) from Algeria.
