The trick to recreating a Shake Shack burger is the sauce. While it resembles other restaurant burger sauces, there’s one key difference: How pickles are incorporated. Typical burger sauces include tiny green flecks of relish. The Shake Shack rendition has no such tell-tale flecks, but still carries that distinctive sweet briny vinegary hit. After a bit of research we determined the best way (and very likely the actual way) to accomplish this a la Shake Shack is to blend the pickles directly into the sauce. It makes for a sauce that’s virtually indistinguishable from the original. Go figure. The most likely the reason you’ve visited one of our Shake Shack restaurants is for our version of the great American cheeseburger. Like all deceptively simple things, it took us years to get it right, but now you can master burger perfection in five minutes. Long ago we threw away the key to the secret recipe for ShackSauce; but we promise to get you really close with ingredients easily found in your kitchen.
