But what if I made stracciatella? The base is still vanilla. I just threw in a bunch of chocolate chunks. |
Whenever anyone else is selling vanilla ice cream, they mean vanilla ice cream. While vanilla ice cream can be made differently, nobody says vanilla ice cream when they mean vanilla ice cream with chocolate chunks thrown in.
Personally, I wouldn't mind as I like chocolate chunks. I'd even prefer it.
Other people hate chocolate chunks, and would not have bought the ice cream if they knew chocolate chunks were in it. By advertising your product as vanilla ice cream, they reasonably believed there would be no chocolate chunks, based on the common understanding of the words. They would therefore feel justifiably ripped off by your chocolate chunk tainting the vanilla ice cream they were promised.
