I missed the initial Ottolenghi discourse but, yet again, Jack displays her tone deafness with pride because the whole myth of his recipes being complicated or featuring obscure ingredients is busted if you have spent any time in a Middle Eastern kitchen. Plus, stuff like za'atar, preserved lemons and dried limes that he uses so frequently are now mainstays in every world food aisle in any supermarket worth its salt.
The idea of him having to take any feedback from a slop merchant like Jack defies belief.
