Roast the couscous in a dry frying pan for a minute or two until the grain darkens very slightly and gives off a fragrant, toasty aroma. Set aside in a glass bowl.
Roast the nuts in the same way, taking care not to burn them, and set aside.
In a small pan, bring the water and apple concentrate to a boil. Pour the liquid into the bowl of couscous, cover with plastic wrap and set aside for 5 minutes.
Remove the plastic and, using a fork, separate the couscous grains. Stir through the nuts and apricots and serve with fresh or stewed fruit and yoghurt. Breakfast couscous keeps fresh for up to 3 days in the fridge.
