In an age when Nando's sell their sauces in supermarkets, it is remarkable that Maccies hadn't gone into full marketing mode and started selling their signature gloop in the shops... until now that is.
The yellow slop, which has mustard, onion, relish, garlic and other stuff in it (feel free to speculate in the comments), has been in Big Macs for years and now, for a limited time, human beings will be able to buy the secret sauce in takeaway tubs.
There's one catch - this is only going to be happening in Australia. If you have any Australian mates, get in touch with them during February, so they can stock-up on it and send you a load in the post (if you're that keen on having some, separate from a burger, that is).
Aussie McD’s are selling special sauce in 25ml tubs for a bargain 50 cents. That's a bargain, eh?
"Big Mac sauce is one of the most iconic McDonald’s ingredients and people often ask us where they can buy it, so we’re excited to be the first country in the world to offer tubs of Big Mac sauce to our customers," said McDonald’s CMO Australia Mark Lollback.
The Aussie wing of Maccies are also auctioning off a 500ml bottle of the special sauce on eBay. At the time of writing, it had reached AU $23,100, which in Sterling, is just shy of £12,000. If that all sounds stupid to you, you could just make your own.
How to make Big Mac sauce
Half a cup of mayonnaise
2 tablespoons of French dressing
4 teaspoons of sweet pickle relish
1 teaspoon of white vinegar
1 teaspoon of sugar
1 tablespoon of very finely chopped white onions
1/8 teaspoon of salt
Mixing them all up in a bowl and leave it overnight in the fridge so they all merge together. Stir it now and then. Bingo bango. You have your own Big Mac sauce.
