half a finger of ginger, peeled and finely chopped
1-2 tbsp ras-el-hanout
1 tbsp harissa paste, plus extra to serve
400g tin chopped tomatoes
400g tin chickpeas
juice ½ lemon
roughly chopped coriander, to serve
Ras el hanout, a North African spice mix, contains cardamom, cinnamon, clove, coriander, cumin, nutmeg, turmeric and black pepper. Find it in larger supermarkets, or use a mix of the spices above.
Tip the couscous into a bowl, season with salt and pepper and stir through 1 tbsp of the oil. Pour over enough hot stock just to cover and cover the bowl with cling film and set aside.
Heat the rest of the oil in a saucepan and cook the onion and carrot gently for 8 mins until softened. Add the garlic and ginger and cook for 2 mins more then stir in the ras el hanout and harissa and cook for another minute. Pour in the tomatoes and stock and give everything a good stir. Season, add the chickpeas and simmer everything gently for 20 mins until thickened slightly then squeeze over the lemon.
Uncover the couscous and fluff up with a fork. Spoon the soup into bowls, top each with a mound of couscous, scatter with coriander and serve with extra harissa for those who want it.
