There have been rumors floating around online forever about the ingredients of the 'Special Sauce' McDonald's puts on their Big Mac.  And apparently, McDonald's has decided it's not worth pretending those ingredients are wrong anymore.

In a new YouTube video, McDonald's executive chef Dan Coudreaut admits, quote, "Quite honestly, the ingredients have been available on the Internet for many years."

And they are:  Mayonnaise, sweet pickle relish, yellow mustard, onion powder, white wine vinegar, garlic powder, and paprika.

He doesn't confirm how much of each of those ingredients you need for the recipe, so that's on you to figure out, but it's clear that you're using MOSTLY mayo and small pinches of the spices.

Clearly, McDonald's isn't making a big deal about these ingredients getting out, and the general public isn't either...this video went up a few weeks ago, barely got any views, and no one in the media noticed until this week.
