William then confessed to hosts Jordan North and Vick Hope that he can’t handle too much spice in his curries, unlike the more culinarily adventurous Kate.

He said: “I can’t do too much spice, I start sweating. It’s not attractive.” Kate replied: “Whereas I like the spice so I have to sort of cook the curry and then add the spice, extra spice at the end.”

Her husband added: “Has to bring it in gently because otherwise I get too sweaty. It’s not a nice sight!”

At the forum Kate made a rare public address underlining the importance of looking after one’s mental health, especially in today’s fas-paced digital world.

She stated: “It is important, however, to remind ourselves of the big picture as we meet here today. What are we trying to improve by focusing our efforts on mental health?

“Ultimately, we are working to build a happier, healthier world. We want to shape fairer, safer, kinder, more equal societies – societies that seek the common good and a better future together.”

William also shared the tips and tricks he uses to ensure he can cope with any mental health difficulties he may encounter.

He explained that “things, like walking, fresh air [and] getting away from screens is a big deal. Having a laugh. Humour for me is a big deal — I love to laugh. You’ve got to look at the lighter things in life sometimes to feel good.”

The Prince added that quality time with his friends and family was also very significant for him, but perhaps he will stay away from the kitchen if his wife is in there.
