Wow! The name says it all. This is the best burger sauce! I scaled this down to 5 servings and followed it exactly. I used Frank's Red Hot for the hot sauce and it was delicious. It does taste just like McDonald's Big Mac sauce. I used this on "The Perfect Basic Burger" from this site. I can't wait to try this again and I'm not one to use a bunch of sauces or condiments on burgers, but this one really is good.
