It depends on the kind of French fries I’m eating.

If they’re the super thin cut like McDonald’s, I’ll eat them 2 at a time dipped in ranch or barbecue.

Curly fries (if seasoned) I’ll eat one at a time no sauce.

Thicker cut fries (steak, crinkle, etc) one at a time with sauce. Sauce can change depending on if fries are seasoned or not.
