Camilla Parker Bowles opened up about Prince Charles' favorite food and what food shouldn't be served to the royals.

The Duchess of Cornwall appeared on "MasterChefAustralia" where she was asked what food the Prince of Wales couldn't get enough of. Camilla was generous enough to share what her husband loves to eat.

"He loves, loves local cheeses," Camilla told the judge Gary Mehigan (via People). "He's a huge cheese fan, anything to do with cheese, he will love."

The duchess added that the next-in-line to the throne couldn't resist "anything with eggs, with a bed of a lot of local vegetables." "He'd love that. You'd definitely see a smile," Camilla added.

When it comes to what shouldn't be served during royal gatherings, Camilla expressed regret for this particular food item. "I hate to say this, but garlic. Garlic is a no-no," the duchess said.

"Because you're talking, chatting?" Mehigan asked the royal.

"Yes, exactly. So you always have to lay off the garlic," Camilla explained.

Darren McGrady, a royal chef at Buckingham Palace, also said the same thing about garlic. According to him, Queen Elizabeth doesn't include it on her menu.

"We can never serve anything with garlic or too much onions. The Queen would never have garlic on the menu," McGrady said.

Meanwhile, aside from garlic, the royals are advised not to eat seafood when on public engagements. This is to avoid possible food poisoning.

"It is a very sensible move to abandon having seafood when out and about on public duties. We don't want a member of the royal family having a serious reaction to food poisoning especially if she is on an overseas tour," Grant Harrold, a former royal butler, told Express.

In related news, Prince Charles and Camilla just enjoyed a romantic evening in Wales. The couple was photographed strolling in the gardens of the Welsh home.

Earlier that day, they visited Llangwm in Wales that celebrated its festival fortnight. The event commemorates the wide range of skills, sport and talent in the village. It also boosts their strong sense of community. Prince Charles and Camilla were also introduced to two magnificent Shire Horses at the Dyfed Shire Horse Farm in Pembrokeshire.
