Whenever a recipe calls for banana leaves, I just usually substitute collard leaves or aluminum foil. But I do see them being sold at Asian/specialty shops in my area.

I haven't had Tamales either. But I remember seeing some that were wrapped in corn husks instead of banana leaves.

Uh Oh. I'd bet Dennis was probably more then just mad

Tinker is right you can probably find them in a good local Asian store. If you have a local Mexican store you probably will find them there as well. Both places should have fresh leaves not just frozen ones. They are also used in Thai fish dishes as well.

Yes, the banana leaves should not be eaten, they are only for wrapping foods and decoration.

And even if you tried, they are difficult to chew. They're bitter and they taste like grass. (Oh wait, how in the world did I know that?! )

I've been looking for banana leaves for a few days in local latin, asain markets and haven't found any.
