McDonald's Big Mac Sauce

I don't have a picture of this, but it is very good & it DOES taste like that special sauce on a Big Mac, so I wanted to share. I got the recipe more than 5 years ago from Top Secret Recipes.
It's a good thing I printed a copy, because I have searched on that site in order to link to it, & I can't find it.
It is said in the into to the recipe that the special sauce is basically a typical thousand island dressing. But, this clone comes closer to the origional special sauce because it has a bit more sweet pickle relish in it than the typical thousand island dressing...and, it uses a bit of French dressing. Just adding ketchup won't do the trick in this sauce.
You can use this to make a Big Mac clone, or just use it on your next hamburgers.
It's good.

Top Secret Recipes version of McDonald's Big Mac Sauce
("Special Sauce")
1/2 c. mayonnaise
2 T. French dressing
4 t. sweet pickle relish
1 T. finely minced white onion
1 t. vinegar
1 t. sugar
1/8 t. salt

1. Combine all of the ingredients in a small bowl. Stir well.
2. Place sauce in a covered container and refrigerate for several hours, or overnight, so that the flavors blend. Stir the sauce a couple of times as it chills.
Makes about 3/4 cup.

I reccomend making this at least the night before. Having it chill just a few hours isn't enough time. I did this once. I thought it smelled too 'vinegary' & when I taste tested it I felt it was good, but too 'vinegary'. Having said that....it was still really good on our hamburgers & everyone raved about it.
So if you like the special sauce on Big Macs, give this a try. You'll like it!
