The Nigella Effect
Fans of Nigella Lawson, celebrity cook, domestic godess and daughter of Nigel Lawson, will only be too aware of the effect that her recommendations can have on the availability of ingredients.
In the run up to Christmas, Nigella has been presenting a series of cooking programmes on BBC2 showing her favourite recipes. In one of them she mentioned that a "must have" staple in her kitchen was goose fat. The fat cooks at a higher temperature than other fats, and consequently produces the most succulent and crisp of roast potatoes.
The consequence of her remark has been a veritable panic buying of goose fat, there is now a nationwide shortage of the product.
I should warn you now, Nigella also tipped something else the other day, which is more than likely to disappear from the supermarket shelves just as quickly as the goose fat; disposable aluminium trays. Her view being that, even though it is not environmentally friendly, using a disposable tray for roasting the turkey and the potatoes saves you a hell of a lot of washing up.
