Step 1

Heat the olive oil in a large flameproof casserole over a medium heat. Add the meat, onion and spices with 1½ tsp salt. Leave for 5-10 mins to lightly brown the meat, stirring occasionally. Add the rest of the ingredients except the lentils, cornflour, coriander and lemon wedges. Add 1 litre of boiling water, bring to the boil, cover with a lid and reduce the heat to low. Leave to simmer for 1 hr.

Step 2

Add the lentils to the casserole, cover with a lid and cook for a further 20 mins. When the chickpeas, meat and lentils are cooked, mix the cornflour in a small bowl with 3 tbsp water, and stir until smooth. Stir the cornflour mixture into the casserole. Simmer for 5 mins until the harira thickens and takes on a velvety texture.

Step 3

Scatter over the coriander, then serve hot with lemon wedges on the side for squeezing over.
