There’s a clip on YouTube by British chef Jamie Oliver, where he asks kids to identify certain fruits and vegetables. Try as they may to employ all senses to help identify, say a tomato, they fall short in this very crucial exercise.
However, when the six-year-olds are asked if they know what ketchup is, they excitedly raise their hands in knowledge, even managing to name a few ketchup brands. You should see the shock and confusion on these children’s faces when the chef finally makes the connection between ketchup and tomatoes.
