At 7 months, and up to 1 year, the idea is just to introduce solid food and gradually move toward more textured food (they have to develop the muscle control over time to be able to handle "lumps" and more solid (adult-like) food).
A bite or two is fine--don't force it. Just try to get her to try a spoonful or two. And if she doesn't like it today, try again tomorrow. And keep trying. Most kids have to try some new foods 10 or 12 times before they'll eat it (very frustrating, I know).
If you're making homemade baby food, be sure you are puree it really, really well. And if needed, put it through a fine mess strainer--Some babies, especially at first, really hate any kind of texture or lumps in the puree.
Try not to get too frustrated and keep trying new foods with her. Its a learning process for them, as much as it's an eating process. So its not so much about nutrition as about exposing her to new things. Making your own baby food means you can make literally hundreds of varieties and combinations and things that the store bought brands don't, and it's more tasty & nutritious. Kudos to you for doing it! :)
