Nigella also had a bestselling cook book before the TV show, and her cook book had a personal and unique take as it was posed as How to Eat rather than how to cook and portrayed a believable description of what Nigella actually cooked for her family and enjoyed eating.
Her TV persona also was very self-aware and slightly self-deprecating in playing up the twinkly lights and innuendo, so she just about got away with her London privileged life.
Even that was just about attainable for many of us, who knocked through our dining rooms and put up fairy lights for 'kitchen suppers'.
M has no establishment as a cook or a host, in fact she seems the opposite and quite isolated. She also has zero self-awareness or self-deprecation, although he trailer seems to be suggesting they are trying to introduce this.
And a Montecito estate and orchard is not going to be attainable for any of us, even if we try to grow a lemon tree in our conservatory.
Nigella would never have suggested putting flowers in ice cubes without a whole nod of self-deprecation about how she knew this was actually quite wanky.
Nigella is very British.
M is very American.
