Mussakhan, one of the national dishes of Palestine, is just one of those dishes that you can’t stop eating once you have started. You absolutely have to eat it with your hands – none of this silly fork and knife business please! – the flavour is just more exaggerated when eaten by hand. In Ramallah, in Palestine, they have just submitted the largest mussakhan, which has been accepted in to the Guinness Book of Records. It is more than 4 metres (13 feet) long and weighs more than 1,350kg (2,976lb) – I would love to have a bite of that! This is a very simple, hearty, full-of-flavour dish that you must try. It should be very oniony and dripping with olive oil. The sumac really is the star of the show and turns the bread a beautiful magenta colour. Auntie Lamia always used to make this when she was coming to the end of her visit to London, before going back home to Palestine – it was always her farewell dish.
