The Duchess of Cornwall took centre stage when the royal visit to the US took in an organic farmers' market in the Californian hills.
Camilla, wearing a navy blue trouser suit, tried local produce, including cheese and salmon fishcake. She later enjoyed half a pint of beer in a pub.
"I'm eating my way around here. Luckily I've got a good appetite," she said.
Meanwhile, Prince Charles talked to farmers as the couple visited the Marin County Market in Point Reyes Station.
The royal couple visited the small town north of San Francisco on the sixth day of their US visit.
The tour has been a diverse one, taking the couple to Ground Zero in Manhattan and to visit people affected by Hurricane Katrina in New Orleans.
At the first stall in the farmers' market on Saturday Camilla was given some Super Rose moisturiser.
Prince Charles patted the bar's dog Fred after drinking a pint of ale.
She dabbed it on her nose and then held her hand out so Charles could smell the organic skin cream.
Susan Adams, owner of the Moonflower stall, said: "I told her that these are products that keep my 50-year-old skin looking healthy. She snapped it right up."
Later Camilla paused at a vat of vegetable soup and thought of her son Tom, who is a cookery writer.
"I should have brought my son with me," she said.
The royal couple then went into an old-fashioned saloon bar called the Old Western Hotel where they were greeted warmly by landlady Judy Borello.
The prince tried a pint of the local Boot Hammer ale while Camilla drank half a pint of IPA.
Ms Borello later said Charles has offered to share his pint with her as she was busy.
"Marvellous, he's a prince of a fella," she said.
As the royal couple went back out into the bright Californian sunshine, Charles patted the bar's dog Fred and then the pair shook hands with a few of the several hundred people who had come to meet them.
