In an interview with Woman magazine, Khoo, who starred in the BBC Two cookery show, The Little Paris Kitchen, said Kate was in her class.
โKate was ill for a few days, so I took notes for her. She was a lovely person, but she kept herself to herself,โ she told the magazine.
On its website, the West London school claims to provide courses โfor interested amateurs of all agesโ that will โinstil a lasting love of good food and wineโ.
Although a three-week course doesnโt come cheap โ costing more ยฃ2000 โ weโre sure the Duke of Cambridge and little Prince George will appreciate Kateโs fine culinary skills.
It might be wise for Prince William to join her next time. He once revealed he was a terrible cook: โWhen I was trying to impress Kate I was trying to cook these amazing fancy dinners and what would happen was I would burn something, something would overspill, something would catch fire,โ he said.
