Camilla, the Duchess of Cornwall, helped bake a batch of organic rolls at the first day of a country show.
The duchess - who is married to Prince Charles - kneaded and shaped the dough and put her roll into a wood oven with six others made by children at the Devon Country Show.
She showed off her baking skills at a mobile bakery run by organic farmer Ian Shears, from Highfield Farm at Topsham, near Exeter.
Shears said: "She was very enthusiastic, very hands on - I was impressed."
About 93,000 people are expected to visit the showground over the next three days. The event is the largest agricultural show in the county calendar and acts as a showcase for Devon's food and farming industry.
Before leaving the Westpoint showground, the duchess went on an unscheduled 100-yard walkabout, to meet members of the public.
She said: "Few things can be as important as reconnecting children, and indeed adults, with the land and helping to understand how food is grown."
