In her book “Kitchen” which accompanies her TV series, Nigella’s Choice names MELLOW YELLOW as her rapeseed oil of choice and says that she uses it “more or less exclusively in preference to extra-virgin olive oil” as “it’s much less expensive and, I’m beginning to think even more delicious.” She also says “I make dressings with it, dribble it on toast in place of butter, douse vegetables with it and take a bottle to people’s houses (so evangelical is my fervour) in place of wine”.
