McDonald’s is giving away a secret recipe for a good cause.
Families with sick children will benefit from an auction of a bottle of special sauce used on Big Mac burgers.
Already, fans are putting their money where their mouth is, with one putting in a bid for more than US$23,000, The Guardian reported Thursday.
The money will go toward Ronald McDonald House of Charities which supports families caring for sick children,
The auction is for the first edition of 200 500 ml. bottles of sauce and runs from February 9 to 11 but it’s only available in Australia.
Altogether, the eBay auction has attracted 135 bids and the auction price may rise further given there is a week to go.
McDonald’s said the bottles “won’t be sold in restaurants. That makes it rarer than a spot on Bondi beach on New Year’s Day”.
“For too long Big Mac Special Sauce has been trapped in a beautiful, delicious burger — now we’ve set it free,” it said.
McDonald’s customers in Australia will also be able to buy 25 ml. tubs of the sauce from any of their outlets this month.
Some people are already trying to sell them on eBay for A$8 (US$6.22) to A$50.
The sauce is known to contain ingredients such as salted egg yolks, mustard, onion, garlic and relish.
The recipe is available online but recreating the exact mix is a challenge.
