It’s a world-famous secret recipe.

Now McDonald’s has announced that fans of their Big Mac Special Sauce will be able to get their hands on a pot of it in Irish restaurants… but only while stocks last.

Big Mac Special Sauce pots will be available from the fast food chain in 50ml portions at 50c each from  February 12th, 2020.

While the iconic recipe has not been revealed, the basic ingredients include zesty mustard flavor, pickle relish, onion powder, and savoury spices.

The possibilities are endless; you could drink it right from the tub, dunk it on your chicken nuggets or use it to dip your chips in. It’ll last roughly a week in the fridge too so stock up if you want to keep the fun going all week.

The chain’s signature burger topping was invented in 1967 by McDonald’s franchise owner Jim Delligatti.

In 1974, the name “Special Sauce” was born, thanks to the famous advertising campaign: “Two all-beef patties, Special Sauce, lettuce, cheese, pickles, onions – on a sesame seed bun.”
