Perfect!!! Agree with others....even better homemade!

I liked that it tastes even better homemaid,I also think it could be a great possibility for burgers or sandwiches. I think I might like it even more without the cayenne pepper

Glad to finally find a good clone recipe - thanks!

If you're a big fan of onion rings from Burger King you probably already
know about the spicy dipping sauce offered from the world's number two
burger chain. Its not necessarily on the menu, and you usually have to
request it. The creamy, mayo-based sauce is obviously inspired by the
dipping sauce served with Outback's signature Bloomin' Onion appetizer,
since both sauces contain similar ingredients, among them horseradish and
cayenne pepper. If you're giving the previous clone for Burger King Onion
Rings a try, whip up some of this sauce and go for a dip. It's just as good
with low-fat mayonnaise if you're into that. And the stuff works real well
as a spread for burgers and sandwiches, or for dipping artichokes
