Another day, another big reveal from McDonald's.
This time the fast food giant has lifted the lid on how they make the nation's favourite fries, as well as what exactly goes into them.
So are the fries actually made of potatoes? Or are they formed from pieces of the moon which have been coated in rubber dust? Well, you're about to find out...

After touring the manufacturing plant in Idaho, former Mythbuster Grant Imahara reveals the news we'd all been waiting for - potatoes feature heavily in McDonald's fries. Hoorah!
The not-so-great news is that there are also 18 other ingredients including beef flavourings (sorry veggies!), salt, dextrose (a sugary substance which helps keep the fries a consistent golden colour) and sodium acid pyrophosphate. The latter stops the fries from going grey. Yum.
But the thing that weirded us out the most is the prevalence of dimethylpolysiloxane, an anti-foaming agent which is also found in skincare products. Although, according to the FDA, it's perfectly safe to consume.
McDonald's UK have since revealed that these chemicals do not feature in fries manufactured in Britain.
A spokesperson for the food brand told the Metro: "The only ingredients in our UK fries are potatoes, vegetable oil (sunflower, rapeseed), dextrose (only added at beginning of the potato season) with nothing added except a sprinkling of salt after cooking.
"Customers can request that their fries be served without salt."
