I teach kids of all ages, anywhere from 3-15.
My current favorite 7-year old (shhh, of course I really don't have any favorites) made some comments recently that made me just want to grab and hug him, especially when his classmates are making "eww" and "gross" noises when we cook with things they don't like.
"I LOVE sushi. I don't like cooked salmon, I only like raw."
On raw chicken (and exclamations of seeing "blood" on it):
"Mmm...I love blood."
On the onions cooking in the sauté pan on the stove:
7-year old: "I think there's caramelization going on in here!"
Me: "What's caramelization?"
7-year old: "Umm, I don't know."
