When it comes to ‘secret sauces’ there are few that are as popular as the concoction found on a McDonald’s Big Mac.

Well, now you can have the moreish accompaniment on anything your heart desires. Anything.

That’s because the good folk behind the Golden Arches have bottled up the popular sauce in support of McHappy Day.

144,000 500ml bottles are now available across Australia so you’ll have to get in quick to grab yours.

Aussies are encouraged to share and post how they are using Big Mac Special Sauce in everyday meals and hashtag #mchappyday to help raise awareness and support families who are going through a hard time.

โ€œWe know that Big Mac Special Sauce has a loyal following, and weโ€™re excited to bring back bottles of this Aussie favourite for our customers for a limited
time,” McDonald’s Australia head of marketing Jo Feeney said.

“Pick up your bottle in restaurants around the country in the lead up to McHappy Day.โ€

Available for $12 a bottle, all profits will be donated to Ronald McDonald House Charities in support of McHappy Day.

In addition to the bottles, $2 from every Big Mac sold on McHappy Day will go directly to Ronald McDonald House Charities.

McHappy Day is on Saturday 16 November. Head here for more information.
