When it comes to gastronomy, Ka Ki values the naturalness of food ingredients and emphasises the retention of their original flavours. She said, “In one of the shows, I visited a farm in the New Territories where I had the opportunity to try a freshly picked corn. It was simply savoury and refreshing. I felt really touched as I was able to have savoured the natural flavour straight from the ingredient.” Since then, she has always been paying attention to proper selection of food ingredients. She considers that food ingredients, as long as they are fresh, will naturally taste good without the need to add too much seasonings.

Ka Ki frequently dines out because of the nature of her work. As many dishes served outside contain lots of meat with strong flavours, she always try her best to keep a balanced diet by bringing along fruits to supplement dietary fibre and nutrients. While eating at home, she prefers bland flavour by just adding little salt and sugar with cooking methods such as streaming and poaching.
