McDonald's recently debuted the Mac Jr. and Grand Mac versions of its iconic Big Mac sandwich and, as part of the fanfare, gave away 10,000 limited edition bottles of its Big Mac Special Sauce. On Jan. 25, the company released an iMessage app that used GPS data to show the nearest restaurant with the coveted bottles; on Jan. 26, customers who arrived and said the secret code - "There's a Big Mac for that" - had the chance to get their hands on one of them.
They went quick and, of course, a few enterprising folks put their unopened bottles up on eBay where, as of Jan. 30, a search for "big mac sauce" yields upwards of 330 results.
If you're absolutely having a Mac attack, they're still available on the auction site, but they won't come cheap; at least a few of the bottles up for start at $10,000 (though they do start as low as $150).
Of course, one could always buy some Thousand Island dressing and save $9,998 or, better yet, make it yourself.
Big Mac Sauce
Simply combine 1/2 cup of mayonnaise, 2 tablespoons of French dressing, 4 teaspoons of sweet pickle relish, 1 tablespoon of finely minced white onion, 1 teaspoon of white vinegar, 1 teaspoon of granulated sugar, and 1/8 teaspoon of salt.
There you have it - your own Big Mac sauce!
