Unfortunately, making a plate of whatever-it-is-new-food for myself does not make him want the food. He'll ask what it is I'm eating, but he'll only ask for a taste if it's ice cream or something that looks like potato chips, crackers, popcorn, that sort of thing. (Pout)

That said? Once he has accepted a food, he rarely turns his back on it. It only falls out of favor with him if I stop serving it on a regular basis.
