Ok, this is probably a really silly question to most of you...but how do you tell the difference between a vanilla and fire? IE: breeding a fire to a vanilla to make vanilla creams? Is it more obvious when they are next to each other? Am I missing something? Am I derpy? Wait...don't answer that

It just seems like they are very similiar, so being me and untrained, was hoping for some pointers. Maybe some side by side comparison shots?

Also!! What do you look for in a quality vanilla? I know what I like in fires, but vanilla's are still up for debate in my head. Pics are always appreciated

Thanks!
