She has the world’s most perfect hair, a perfect wardrobe, a perfect husband and perfect children, but there is one thing that Kate Middleton has not quite perfected.

The Duke and Duchess of Cambridge stepped out for a special formal summer dinner to benefit the East Anglia’s Children’s Hospices, and while the menu at the event was provided by five Michelin-star chefs, it was Kate’s cooking skills — or lack thereof — that drew the laughs.

“William has to put up with my cooking most of the time,” Kate told the chefs.

William added, “It’s the reason I’m so skinny.”

What? There is something in this world that Kate cannot pull off with perfect aplomb? I don’t believe it for a second.

It’s not as if she doesn’t get enough practice. While the couple does employ a nanny and a housekeeper at their royal residences, both at Kensington Palace and their country home at Anmer Hall, they do not employ a cook, and Kate by all accounts is in charge of family meal times.

“Aides insist there is no in-house chef — Kate loves to cook, and she has been spotted buying local produce at Back to the Garden,” Vanity Fair claimed in a recent article about the royals. “Mealtimes are hectic family occasions with pots of food served straight to the table.”

One of the first candid shots of Kate taken after she gave birth to Prince George was of her doing the grocery shopping near the couple’s former home at Anglesey, and she was often seen at U.K. grocer Waitrose stocking up on essentials like chicken, lettuce, bananas, milk, potatoes, oranges and ice cream.
