McDonald’s famous sauce is the basis of just about every “burger sauce” in the game. The transformative sauce is being given away as part of a promotion for the continuing overhaul of the McDonald’s menu. This would include two new Big Mac sizes, a chicken McGriddle and a variety of other options. If you’re wondering what a plastic bottle of burger nectar looks like, Twitter has all the answers you need.

On January 26th you too can begin your hunt for the new sauce, using a McDonald’s Big Mac Special Sauce Finder. The app is available on the app store and will let you know where to acquire the fast food liquid holy grail. If you can’t locate the sauce bottle, fear not, since they are giving them away if you follow their social media accounts.

If all else fails, you can resort to making the sauce yourself like the layman you are.
