My mother used reverse phsycology on me, she'd say if I wouldn't eat it, "GOOD, MORE FOR ME!!!" Then she'd sit there completely enjoying the food! With my kids, I used similar tactics, their father also let them taste stuff like Ranch dressing when they were still in the high chair. They loved it. You have to SELL the food, and it really has to taste good when they finally try it, otherwise they won't believe you the next time. Dad used to give me raw oysters when I was little, I loved them. They had lots of flavor! Don't be afraid to use seasoning and butter.
