Jamie Oliver has donated a recipe to a £5 charity cook book going on sale in the village where he grew up.
Oliver's offering is listed alongside hundreds of recipes from lesser known cooks in Clavering, Essex.
Culinary Memories of Clavering, which goes on sale in the next few weeks, will raise funds for the local church.
Editors are keeping the details of Oliver's recipe a close secret.
"All we are saying is that it is a pork recipe," said Rosaleen Nagle, who had the idea for the book.
"By keeping it secret we hope that more people will buy the book to find out what it is."
She added: "We were delighted when he agreed to help. His name is bound to help sales."
