Gaynor will be demonstrating her favourite recipes in the Celebrity Cookery Theatre on Sunday, September 16, alongside Masterchef winner Jane Devonshire.
Gaynor said: “I’m very excited to be making my Food Festival debut in the stunning grounds of Clumber Park. I can’t wait to share my passion for cooking and regional produce with likeminded food fans.”
Bev Channell, Festival of Food and Drink organiser, said: “We’re very excited to welcome Gaynor to Clumber Park in what will be her first appearance at this type of event. Being on the South Yorkshire border, Gaynor’s style of cooking fits perfectly with our visitors.”
Tickets are £7 in advance.
