McDonald's To Give Out Free Bottles Of Big Mac Special Sauce

PITTSBURGH (KDKA) -- The Big Mac was invented in Uniontown by the late Jim Delligatti, 50 years ago. And he never divulged the secret of his trademark "special sauce."

Fast forward to 2017.

For the first time ever, bottles of special sauce will be handed out to the public. The first 100 customers at McDonald's in Dormont will each receive a bottle at 1 p.m. on Thursday. National Menus Innovator Mike Harasz says 10,000 bottles will be given out nationwide.

"You're actually able to pick them up for free. But it is a first come, first served basis. So once we're out, we're out."

Chef Mike Harasz helped come up with the idea to make the Big Mac bigger, and smaller. Last November, Pittsburgh was the test market for the Mac Junior and the Grand Mac, to see how they sold. City residents must have eaten a lot of them, because they soon went nationwide.

Back to the special sauce giveaway -- we managed to convince Chef Mike to divulge the secret of the special sauce.

"Our special sauce is actually like a mayonnaise, mustard, pickle, relish-based sauce. A little onion and garlic. We ensure that wherever it's made, it's consistent throughout the United States and everywhere else."

All locations for the Thursday giveaway will be released Wednesday on McDonalds.com.

Michael Delligatti, son of the late creator of the Big Mac says now that the secret to their special sauce is out, "What can I say? My dad, he passed away a couple months ago and now the secret's out."

Delligatti says that the 100 free bottles of special sauce will be given away at the McDonald's on West Liberty Avenue Thursday at 1 p.m.

"That's the only one where they're going to distribute [the special sauce]," says Delligatti.

Also, if you want your own bottle you have to tell the cashier "There's a Big Mac for that."
