April 1 (Bloomberg) -- Jamie Oliver, the U.K. chef best known for television campaigns to train unemployed youngsters and to improve school meals, will do his best to help ease the world economic tensions tonight with a dinner for world leaders.

Oliver’s Downing Street menu for the G-20 summit will feature British produce such as fresh organic farmed salmon from Shetland and shoulder of lamb from the Elwy Valley in north Wales. Oliver will be helped by a team of eight young cooks who learned their skills at his Fifteen restaurant in London.

"I’m very, very proud of my country and its food traditions and I know that the guests at Downing Street will be in for a real treat," Oliver said today in an e-mailed statement.

This will be Oliver’s third time in the kitchens at 10 Downing Street. He previously cooked for then-Prime Minister Tony Blair and Italian President Massimo D’Alema in 2000 and for Tony Blair and the Irish leader Bertie Ahern in January 2003.

The straightforward menu of salmon, lamb and tart shouldn’t give anyone indigestion or attract criticism as extravagant.

The meal will include Irish soda bread baked on the day using Gloucestershire-based Shipton Mill organic flour and a Bakewell Tart featuring Grasmere ginger shortbread. The custard will be made with eggs from the Prince of Wales’s Duchy of Cornwall farms.

The butter will have been freshly churned at Fifteen London using organic cream from Ivy Farm in Somerset and smoked sea salt from Halen Mon in Wales.
