Natalie Coleman - winner of this year's series of MasterChef on BBC One - switched on the Borough Market Christmas tree lights on Wednesday evening.
"It's my favourite place and like an Aladdin's cave," said Natalie who thanked the market traders, including Turnips, Furness Fish and Ginger Pig, for giving her time and advice.
"When I did MasterChef I did shop here for everything," she added before leading the countdown to switch on the lights outside Roast.
The ceremony took place on Wednesday evening following Southwark Cathedral's annual Christingle service when Mike Sobers, representing Better Bankside businesses, read the Annunciation story from St Luke's Gospel and children lit their Christingles.
After the lighting of the cathedral's Christmas tree, the congregation moved to Borough Market to be welcomed by managing director Keith Davis.
Donald Hyslop, chair of the Borough Market trustees, read a passage from St John's Gospel and the Dean of Southwark, the Very Revd Andrew Nunn, led prayers for the traders and customers and the work of Crisis and local homelessness charities Robes and the Manna Centre.
The market will be open every day from Wednesday 11 December till Christmas Eve, with late night markets on Thursday 12 and Thursday 19 December.
