Heat the butter in a saucepan on medium high heat and fry the couscous for about 2 minutes until lightly fragrant.
Add salt and stir to mix.
Take the saucepan off the heat and leave to cool for a minute to reduce the splattering when pouring the boiling water.
Pour the boiling water onto the couscous in the pan, stir and cover with a lid. Stand a little away from the pan in case the couscous does splatter, you don’t want to get burnt.
Leave to stand, covered, undisturbed for 5 minutes.
After the 5 minutes, get a fork (not a spoon) and gently fluff up the couscous thoroughly. TIP: Using a spoon will result in clumps.
