What about milk? People put all kinds of fruit and cereal into milk.
Lots of soups have no added food, but I'm assuming you had that in mind when you made your post. So my question is, for example, should you have vegetable soup with some chunks of vegetable in it, and you remove those vegetables and still have the liquid remaining, does that instantly change that soup from "not drink" to "drink" the moment that last bit of food is removed? If this is the case, what happens when someone makes cocktail that has a berry or lime in it?
