The famous fries start as Russet Burbank potatoes on the farm, in this case Leveque Farms in New Brunswick, Canada.
The farmers use this machinery to harvest the potatoes.
The potatoes are then moved to a truck using a giant conveyer belt.
The fries go through a machine to remove dirt and grime. Once that's done, workers look to see if the machine missed anything.
Next, the potatoes are loaded into a truck and transferred to a processing plant along with potatoes from 30 other farms.
The potatoes are washed clean.
Next, they are peeled by machines.
Then, they are once again examined for imperfections before being sliced.
Here's the part of the machine that slices the potatoes into the fries.
Now, the potatoes are sliced and ready to be blanched. The blanching process strips the natural sugars and keeps them from turning different colors.
McDonald's also adds dextrose solution and other ingredients to keep the potatoes from turning grey. The strips are then dried out and quickly fried.
The fries are frozen and packaged for restaurants.Now, they'll be shipped to McDonald's locations.
The fries are cooked in 100% vegetable oil.
Once cooked, the fries are salted and put into the signature red containers.
