Oh dear. I don't want to ban anyone, so listen up.
Here's the deal for everyone to cope with if they have either read the manga or heard about what happens after the coming filler arc: If you bring up anything that hasn't yet been mentioned in the anime, you had better use a spoiler tag. This particular spoiler won't be mentioned until after the filler arc, so you'll have to keep your lips zipped for a long time.
It will be tempting to use your spoiler knowlege to debate a particular point, so don't even think about debating it. You know what I mean. For any anime-only watchers reading this, don't worry about it too much if manga readers seem antsy about a particular point. They don't really know the answer, but some of them think that something is a lot more important than it might turn out to be.
Now here's a tutorial for using spoilers:
[spoiler=Bleach manga chapter 1234]
Finally we know the truth! Ichigo's inner hollow manifested as a result of eating his dad's cooking.

Spoiler for Bleach manga chapter 1234:
Ichigo's inner hollow manifested as a result of eating his dad's cooking. I'm shocked how bad a chef that old man really is!
It seems that the only way for him to bring his hollow under control and
gain its powers for himself is for him to eat the cooking of the girl he loves. I guess the way to a man's heart really is through his stomach. Now we're down to a cook-off between Ururu and Nemu! We'll finally know which girl Ichigo really loves, when we see whose food can grant him the ultimate power of a true hollow-shigami fusion.
I hope that the right girl is Ururu, since Nemu is such a bad cook that she nearly killed Ishida with her last attempt to make takoyaki for Ichigo. He's a real trooper to try recipees intended for Ichigo, but I suspect the real reason is that he's just happy to eat her food.
Maybe she'll eventually realize who really loves her, by who she brings joy to with her cooking. By comparison Ururu's food is so good that if she can bring the hollow under control, Ichigo might actually be able to defeat Aizen's ultimate shushi combo. I doubt badly made food can give Ichigo that much power even if he does love the girl.
