Add the meat again, along with the spice mix and garlic from the mortar. Lightly fry for 1 min. Add the chopped tomato, gently fry for 1 min, then add the fired tomato sauce. Add the stock and leave to cook with the lid on for around 25 mins. When the meat starts to become tender, add the lentils, chickpeas, parsley, coriander, saffron, chopped dates and raisins.
