Can't get my 8 month old to eat jarred strained food.?

I have other children and all of them graduated from strained jarred food, to chunky jarred food, then to finger food all by 9 months. My daughter eats pablum, but after that will only eat jarred strained food. She gets so upset at the look of chunky food she will make herself projectile vomit. Somtimes before I even get any into her mouth. I've tried making my own baby food, as I did for my other kids, but again, she tastes it, and spits/gags it all out. Any ideas as to why? Thanks!
