At a celebration honoring the National Health Service of the United Kingdom’s 75th anniversary, the Princess of Wales received some professional advise from Alice Fevronia.

Kate Middleton is receiving advice from culinary experts!

When the Princess of Wales and Prince William joined Great British Baking Show finalist Alice Fevronia at a recent celebration to honor the 75th anniversary of the U.K.’s publicly-funded National Health Service (NHS), she and William received a mini-lesson in cake-making.

At the Big Tea Party put on by NHS Charities Together, Kate and William, both 41, assisted by giving Fevronia’s tiered cake and cupcakes some last touches.

Kate placed the NHS-themed cake topper to the main cake and was quite curious about Fevronia’s skill in designing it.

She said, “She said that on a few of occasions, she had stayed up rather late trying to decorate the kids’ birthday cakes.

Princess Kate reportedly inquired “about how to get the sides of the cake straight and smooth,” according to Fevronia. I switched into teaching mode because I used to be a teacher. Right, this is what you need to do, I said.

She tells PEOPLE, “That was quite cool that I got to sort of give her some tips!”

She continues, referring to William’s own attempts at cake decoration, “The prince’s piping skills were, shall we say, less good than the princess’s.”

Regarding the royal couple, Fevronia adds, “They were just really fun.” They were merely enjoying themselves.

The Baking Show alum’s partner is a pediatrician who works long, demanding hours, and many members of her family have worked for the NHS.

“The royal pair enquired. What are his stress-reduction and relaxation techniques? And because it’s such a busy work, I believe it’s making sure there are people to talk to,” she says.

NHS Organizations Together offers mental health support to NHS workers, and the celebration for staff members and former patients was hosted in a London hospital’s wellness garden. While the NHS offers free care when it is needed, there has always been a reliance on regional nonprofit organizations to help fill in the system’s gaps and provide additional support to hospitals and medical facilities.

Aneira Thomas, from Swansea, Wales, who was the first child to be born under the NHS, 75 years ago today, was one of the important persons Kate and William visited during their tour.

Around a minute after midnight, Edna’s mother, Thomas, appeared to heed one of the physicians’ exhortations to “hold on” in order to deliver the first child in the brand-new healthcare system. She tells PEOPLE that “it is central to who I am and I wanted to shout it from the rooftops.”

The baker continues, “It was such a beautiful day. The sun was out. Simply put, the environment was amazing. There were so many incredible members of the NHS there, each with a wide range of roles or links to the organization.
