The UKs largest barbecue has gone on sale at Tesco, complete with five gas burners and a kitchen sink.At just under ten feet in length, the Landmann Kitchen BBQ has a substantial preparation area and storage units for storing any equipment, the Daily Telegraph reported.The model uses bottled gas and users can connect the sink to the garden hose, but outdoor cooking fans will have to pay a whopping 1,599 to get their hands on the new barbecue.With a series of major sporting events taking place this summer and forecasters predicting the best weather for four years, Tesco hopes its wealthier customers will be encouraged to splash out on the barbecue.Brian George, president of the National Barbecue Association, said One of the problems with BBQs is lack of preparation area so I think this is a great idea. Barbecues are emotional escapism and they often have very big BBQs on the continent.This week, a report in the Calgary Herald noted that stainless steel appliances can give a kitchen a gourmet appeal.
