After years of criticism, McDonald's in Canada have decided to go down the brutally honest route with their latest campaign.
First they confessed to the amount of photoshoppery that's involved in their burger pics and they're now going one step further to screw with the American framework of secrecy.
In this video, their executive chef Dan Coudreaut responds to a consumer question about what's included in the Big Mac sauce by making the whole damn thing for us to see.
If you're keen to replicate a late night drunken mistake in your own home then all you need is mayonnaise, sweet pickle relish, yellow mustard, vinegar, garlic powder, onion powder and paprika.
PR win for McDonald's. Again.
