Jamie Oliver has been invited by Gordon Brown to prepare a banquet at No. 10 for President Barack Obama and other leaders of the G20, offering a cut-price menu to reflect times when trade and industry are far from prosperous and the rate of employment is decreasing.

Downing Street sources say Oliver, the well-known chef, will cook using “honest high-street products” and avoid expensive or “fancy” ingredients (材料).

The prime minister is trying to avoid a repeat of the embarrassment last year when he sat down to an 18-course banquet at a Japanese summit to discuss world food shortages.

Obama, President Nicolas Sarkozy of France, Chancellor Angela Merkel of Germany and other leaders will be served by apprentices (学徒) from Fifteen, the London restaurant Oliver founded to help train young people in poverty in order to make a living by mastering a skill.

Brown wants the dinner to reflect the emphasis of the London summit, which he hopes will lead to an agreement to lift the world out of recession. “To be invited to cook for such an important group of people, who are trying to solve some of the world’s major problems, is really a privilege,” said Oliver.

“I’m hoping the menu I’m working on will show British food and produce is some of the best in the world, but also show we have pioneered a high-quality apprentice scheme at Fifteen London that is giving young people a skill to be proud of.”

The chef has not yet finalized the menu, but is expected to draw inspiration from his latest book, Jamie’s Ministry of Food, which has budget recipes for beef and ale stew (啤酒炖菜) and “impressive” chocolate fudge cake.
