Jan. 25 (UPI) — Ever wonder what McDonald’s puts in its Big Mac “special sauce?” Well, the burger giant won’t give away that secret — but it will give away thousands of bottles of the famous concoction on Thursday.
The restaurant announced the giveaway this week after unveiling two new versions of the iconic Big Mac sandwich — a smaller Big Mac Jr. and larger Grand Big Mac.
Wednesday, the chain announced which U.S. locations are involved in giving away 11.4-ounce bottles of the legendary condiment.
“The Big Mac Sauce is unique to McDonald’s and includes a classic combination of ingredients,” McDonald’s spokeswoman Becca Hary said in a statement. “The Bic Mac Sauce remains timeless and customers around the world continue to enjoy its signature taste.”
