I heard a snatch of this when it was Book Of The Week (quite some time ago) and have been meaning to read it ever since. A sort of autobiography covering the formative years, with each vignette prompted by or focused around a particular food.
You see, Proust's madeleines don't really evoke anything if you're not French, do they? But Angel Delight, spaghetti bolognese, toast indeed, do evoke memories.... Don't be deterred by the fact that he's a chef. He is (like Nigella) a writer as much as a cook.
