My baby prefers store bought baby food :( Help!?

My little guy has been eating solids for about a month now and up til this point, I've used store bought baby food. Recently I decided to prepare my own using a great little cook book that I found. Trouble is, Tommy doesn't like the stuff I make! I've tried him with homemade squash, peas, yams and carrots but he refuses to eat any of it. I think the texture of my food is different from what he's used to despite me pureeing the heck out of everything. Ultimately I know that homemade food is probably better for him and less expensive for me but how do I get around this? He shuts his mouth up tight and cries when I put it in his mouth. Should I persevere with this or go back to store bought??
