My kids actually never had baby food from jars. Right around the time my kids were born (19 yrs ago), there was a big deal in the news about glass being found in Beechnut baby food. (Do they even make that anymore?) Anyway, I was scared by that, plus we had soooo little money and baby food was so expensive. My grandmother had raised four kids during the depression, and jarred baby food wasn't even invented then, so she showed me how to make my own food. Food processors make the job so much easier.
I just graduated the textures all along the way. As the boys got older and teeth came in, I made the food less and less smooth until they were eating whole foods. If your little one still likes the texture of the jarred food, you might try making your own to the texture that she likes. That might ease her into trying some of the new foods. The texture really affects the taste a lot, and maybe she's having a hard time going from foods that are mostly smooth to whole food form. Hey! I like grilled cheese sandwiches, but I bet I wouldn't like it in pudding form! That could work the other way round for babies.
Also, you have to try new foods over and over again. What's that "magic number"? It's something like 15 times before they'll actually like a new food (and yes, sometimes never!) Just try little bits again and again, experiment with different textures, and you may hit upon the right combo.
