We had a "try something three times" rule. I read that the first time, it tastes weird, second it is a little familiar, and by the third, you have developed a taste for it.

My daughter is 12 and loves every vegetable and all types of food. She loves Indian, Ethiopian, you name it.

Usually on her second try, she would put it down and say "free times Mommy!", but she always ended up loving it.
