Pirongia bachelor Ken Veen says his own cooking skills greatly improved after the workshop.
Mr Southon is a New Zealand celebrity chef and television personality.
He is the current resident chef for the New Zealand morning TV Show The Cafe. Michael Van de Elzen was Friday's celebrity chef.
You may know him from TVNZ's top-rating show, The Food Truck, which was about tackling the fast food industry in an old Bedford truck called Beddy.
On Saturday, Karena and Kasey Bird entertained the crowds on the final day of Fieldays. The sisters from Maketu were the 2014 winners of MasterChef New Zealand.
