"This is an excellent line-up of top chefs who regularly appear on our television screens and are therefore extremely well known to show goers," said Elwen, who is HCC's Consumer Executive.
"Cooking demonstrations by leading chefs are an enormous draw, and I expect this year to be no different," she said.
"The HCC stand is a perfect venue to show off their skills, since it has a raised cooking area and seating for up to 40 people with plenty of room for many more to stand and watch the action."
Francesco Mazzei, Chef Patron of L'Anima in London will be at HCC's show stand on Monday and Tuesday (23rd & 24th).
A regular of TV programmes including BBC1s Saturday Kitchen, he is an enthusiastic advocate of Welsh Lamb and is a member of HCC's Welsh Lamb Club, a group of chefs and leading restaurants.
He has helped promote Welsh Lamb in conjuction with HCC during the Taste of London events in 2011 and 2012.
