Burger King’s Zesty Sauce is probably the most unique sauce they have, at least in the United States. It’s also my favorite sauce here. Primarily meant for onion rings, the Zesty Sauce has a ton of ingredients that separate it from the sauces of its fast food competitors.
The primary ingredient in this is a horseradish sauce. Unlike Arby’s horseradish sauce, which is mostly just straight horseradish flavor, Zesty Sauce has tomato paste, eggs, lemon juice and spices. This stuff actually has a little spiciness to it, and I don’t mean that mustardy heat that you normally get from horseradish or wasabi.
Among all the sauces at Burger King, this one is my go to. It has the right mayonnaise-like consistency, but with the spice and additional flavors to make it interesting.
