Michel Roux Jr, Raymond Blanc and Jason Atherton are just some of the 100 top chefs helping to raise money for charity by taking part in this year's Mince Pie Project.
Raising money for FoodCycle and Kids Company, the project includes a mince pie auction and a raffle of baked goods from leading chefs. Serving meals to the millions of people in Britain at risk of food poverty and isolation, charity FoodCycle seeks to unite volunteers with surplus food and spare kitchen space; while Kids Company aims to provide practical, emotional and educational support for inner-city children.
To take part, each chef must create two boxes of mince pies of their own design, one of which is then auctioned and sold to the highest bidder. The second box is put in a raffle, for which tickets cost £2 each.
Last year the event raised more than £30,000, with Michel Roux Jr's 2012 box taking £470, Raymond Blanc's netting £360, Nigel Haworth's taking £255.20 and a box from Edd Kimber (winner of the first ever BBC Great British Bake Off) selling for £255.
Dan Doherty of Duck and Waffle currently holds the auction record having sold his box of gingerbread-flavour pies for £1,900.
Former years' bakers have also included Angela Hartnett, Bruno Loubet, Bryn Williams and Claude Bosi. This year sees Michael Caines, Marcus Wareing and Tom Aikens join the line-up.
Chefs can be as creative as they choose: past examples have included deep-fried mince pies from Dinner by Heston Blumenthal chef Ashley Palmer-Watts (which last year sold for £1,000 a box), sweet potato mincemeat and even mince pie macarons.
Submissions for the online auction begin at noon on 6 December and end at noon on 13 December.
Michel Roux Jr said: "It's exciting to be involved in The Mince Pie Project again this year. It's a unique project involving creativity and healthy competition to raise money for a great cause during the festive season."
