> Are the rules similar to cooking rice?
Ah; that'll be why you get wallpaper paste...
No, for cous-cous, simply boil the water, pour over the cous-cous, and leave for five to ten minutes. That's why it's so good for camping, as it doesn't need all that simmering that rice or pasta does, hence saves fuel. Works even better with a cozy to keep the pot warm whilst it 'cooks'.
e.g. here are the instructions from Sainsbury's flavoured cous cous:
How to cook.
Boil in 7 minutes.
1. Melt 10g of butter or margarine in a saucepan.
2. Add the contents of the packet and gently cook over a moderate heat for 1 minute.
3. Add 200ml of boiling water and bring to boil.
4. Remove from the heat, cover and stand for 5 minutes.
5. Return to the heat for 1 minute, stirring with a fork to separate the grains.
I skip steps 1, 2 & 5...
