answer:What I read a while back is you have to put the fresh slices of potato in some sort of sugar water. Then deep fry them. I think it was in vegetable shortening, but possibly that is against the law now, or maybe McDonald’s chose not to use it anymore on their own, or maybe they still use it, I don’t know. I know some fast food places stopped using it. Then they refrigerate the fries. Then they refry them, and I am not sure if it is in hydrogenated fat again or possibly lard. I don’t know if they claim the fries are vegetarian or not. What I read was not an insider from McDonald’s, but one of those at home copycat type recipes. I do remember one of our jellies here used to work at McDonald’s and she said the fries do have sugar in/on them. Hopefully, she will see this Q, I don’t remember her name.
