This is a superb – and complete ­– dinner. Baharat, aka Arabic seven spice, is a heady and aromatic blend of spices that includes pepper, cumin, cloves and cardamom, and is used extensively throughout the Middle East. Unsurprisingly, it’s a perfect blend in which to marinate lamb, and is delicious here tossed through the burghul salad with its sweet dates, salty and bright preserved lemon, and creamy tahini yoghurt.
