A chef who has won a competition to cook a dish for the Queen to celebrate her 80th birthday has pledged to source all the ingredients from Wales.
Chef Bryn Williams wants to show what food Wales can offer
Bryn Williams, 28, from Denbigh, beat chefs from around the UK to win the public's vote in the fish category in the BBC series The Great British Menu.
The recipe he created will be served to 350 guests at the birthday dinner at the Mansion House, London, on 15 June.
He said: "We need to show people outside Wales and the UK what we have."
Mr Williams, sous chef at the Orrery restaurant in London, clinched the palace order in the televised final hosted by the BBC's former royal correspondent, Jennie Bond.
The former Ysgol Glan Clwyd pupil, who trained at Coleg Llandrillo Cymru in Colwyn Bay, impressed judges with his dish of pan-fried turbot with cockles and oxtail.
He and the chefs who developed the other three courses to be served meet their Mansion House counterparts on Thursday to talk through their techniques for cooking their dishes.
He said: "We can't work without them. We did it for four judges and that was enough pressure. They (the Mansion House chefs) will be cooking and I want to get stuck in to make sure it goes out the way I want it."
Mr Williams said the secret ingredient in his dish was sea beet, which he described as "salty spinach".
'King of fish'
He said he will source it from a firm which gathers the leaf by hand from estuaries in north and west Wales.
He said: "This dish is the best of Wales, both the sea and the land and, with the sea beet, the bits in the middle, the estuaries.
"I wanted to use a good fish. I do know you can get turbot from the north Wales coast. I think turbot is the king of fish.
"All the oxtail will be from Welsh back beef, from butchers in Conwy. I just want to prove that we do have some good ingredients in Wales."
The Great British menu competition featured heats with 14 chefs representing seven different nations and regions.
The judging panel included Prue Leith, Matthew Fort and Oliver Peyton, as well as the public vote.
A behind-the-scenes look at the Mansion House lunch, presented by Jennie Bond, is screened on Friday 16 June at 1900 BST on BBC TWO.
