It helps to avoid phrases such as 'Mariam's couscous is really tasty'.
Couscous is a small grained semolina, made from durum wheat and used throughout North Africa and the Levant. The packs you buy in supermarkets have been pre-steamed, but the original stuff of North Africa is steamed over a broth. This means that supermarket couscous can be prepared simply by adding boiling water or stock, then fluffing it with a fork after it's soaked for a few minutes.
Buying pre-flavoured couscous, particularly with some daft chef-goon's face on it, is a terrible thing to do. What a waste of money and what a terrible thing to eat: all nature identical ingredients that fill your mouth with the neon plasticity of too-strong, too-bright flavours.
No. Be an adventurer. Make your own couscous. Then add things as you see fit. Try it with a tagine or pop in some grilled vegetables to make a salad. Or make it with a strong stock and just have it nice and plain.
