For one group of children aged between ten and fifteen, Saturdays are spent learning the art of serious cooking. Their weekly lessons in small classes are so popular that there is a waiting list of 30 children who want to do the course. Parents pay £280 for the course where their children can have fun and learn how to make good food.
Class member Bill, aged ten, says, "I love my mum's cooking and now I can do it better than her. The teachers make us laugh, especially when we sit down with them to share the food we've made."
Flora is twelve, and she’s having problems preparing onions. “I love cooking. I did a meal for ten friends which they really enjoyed. Then my mum suggested I take up a hobby, instead of doing nothing at weekends. I was happy staying at home, so I wasn’t too keen at first. I’m really glad I decided to come, though.”
Their teacher, Philippe, says, “It’s great fun. Children pay attention and remember things better than adults, although the kitchen isn’t always as tidy when they’re cooking! As adults, we’re always learning more about food. If parents interest their children in cooking when <they> are young, they’ll have enough skill to make food for themselves when they leave home.”
