7. McDonald's finally gave up the special sauce secret back in 2012
For some reason, it took the fast-food giant nearly 45 years to unveil the recipe that everyone who's ever had the pleasure of tasting a Big Mac absolutely knew -- mayo, sweet relish, yellow mustard, vinegar, garlic powder, onion powder, and paprika. Thanks, guys.
8. And the company uses a "specially" calibrated gun to spread said sauce
It gets weirder, though. Apparently, the special stuff is delivered to each McDonald's franchise in custom "sauce guns" stocked with sealed condiment canisters. With each trigger pull, the machine fires precisely measured dollops of the tangy condiment onto each lucky burger.
