I live in the Gulf and before I moved here I was seriously obsessed with Ottolenghi. But now I am actually here I can see that real Middle Eastern food is nothing like what is in these books.
It is simple fare, not mucked about with, designed to be prepared and cooked on the move with few ingredients and minimal equipment. I.e. No lemon zesters and no Poggenpohl kitchen. What these books offer is poncey middle class British recipes which sometimes use vaguely Middle Eastern style ingredients.
Most Emiratis I know would shudder at the thought of chopping up dates and throwing them in a salad. They are meant to be enjoyed in their own right and come in a hundred different varieties, all of which taste different.
My tea tonight was
Flat bread
Houmous (just plain, nobody does flavoured houmous here)
Kibbeh
Cheese samosas
Olives
Fattoush
Chicken kebabs marinated in Arabic spice mix
No ponciness at all. If I was pushing the boat out I would have gone for some stuffed vine leaves too. Or some lamb and rice.
As if it couldn't get worse, I died a little inside when faced with Jamie Oliver's Comfort Food shawarma recipe. Blasphemy 
So, whilst I don't mean to piss in anyone's pilaf, don't be fooled into thinking you are getting real Middle Eastern food from Ottolenghi or Persiana - I'm sure it's perfectly delicious but if you want authenticity, find a Lebanese restaurant (or an Emirati one if you live in London), go in, befriend the chef, ask them all about how they make their bread, or houmous, and pay him or her to give you and your foodie friends a cooking class when the restaurant is quiet and then write down their recipes. That's what I do here! If you can find a book called Sarareed by chef Khulood Atiq, this is a good intro to real Emirati food if anyone is interested.
