@mattskala @lain Interesting fact about McD French fries. The suppliers they contract have special cutter dies and use specifically graded potatoes to make the chips come out within exacting size specifications.
McDonald's also supplies bags if powdered ingredients that the fry factories are required to add to the brine they blanch the fries in. The exact ingredients are not disclosed to the supplier.
Not even the makers of the fries know what is in them...
