It was on the Christmas programme and I've managed to find the lamb and date tagine recipe but with it she had a red onion and pomegranate salad. She did something to the onions - soaked them in lime juice and pomegranate juice or something, but I can't remember what and I REALLY want to make this for Christmas Eve. Anyone? Not sure if it's in Nigella's Christmas recipe book but I don't have it.
