The Hamburglar, yes, Hamburglar stopped by the Houston Press today to drop off a bottle of Big Mac Special Sauce and share some interesting news. Today, January 26, McDonald's across the country are giving away limited-edition bottles of the sauce — there's only 10,000 total. In the Houston area, five locations will be handing out some 250 bottles of the product.

The giveaway also corresponds with McDonald's introduction of two new Big Mac sizes, a smaller Mac Jr. or a behemoth Grand Mac.

So what is Big Mac Special Sauce exactly? There are too many ingredients to actually determine this, but it tastes rather like sweet, oniony mayonnaise (or Thousand Island dressing, really) with bits of actual relish and the ghost of Big Macs past in the mix. Use it to perhaps elevate your basic sandwich or tater tot game at home or to impress all your gamer friends.

Houston chefs Antone Ware of Harold's in Houston Heights and Rishi Singh of Batanga have both highlighted the sauce's culinary potential by creating specialty dishes in collaboration with McDonald's for the giveaway: deep-fried deconstructed Big Mac balls (have mercy) and a po-boy, respectively.

To get your hands on a bottle, visit any of the following locations at the given times. There will be designated giveaway areas, and you'll have to say the phrase "there's a Big Mac for that" to even dream of getting your hands on a bottle.
