McDonald’s latest installment of the digital series “Our Food. Your Questions.” --which tries to debunk myths about the chain's food -- goes behind the scenes of how America's most favorite fast food french fries are made. 

While some might assume they are made with lots of different chemicals, the fast food giants have confirmed the main ingredient is just a potato.

“I’ve been asked by people are the fries even made out of potatoes? Are they ground up and mushed into the fry shape?” former "Mythbusters" host Grant Imahara asks as he walks through a super sized potato production plant.

Instead of going from farm-to-table, Imahara reverses the process—taking viewers from the fryer to the farm.

First, the potatoes are peeled and then cut into a fry shape.

Next, they are dipped in dextrose natural sugar) to maintain a golden color, before being treated with sodium acid pyrophosphate which prevents the chips from going grey on their way to the fast food outlets.  

Yes, the fries are partially fried and then frozen, and yes they contain a few un-pronounceable additives to maintain consistency. But that’s why they always taste so good. 

Check out the whole process behind the signature McDonald’s fry.
