This secret ingredient isn't something you'd suspect would be good on a hot dog, but you HAVE to try it!

At a typical cookout, you've got the usual fixings: Ketchup (ew!), mustard, onions, relish, etc. While those are all fine and good, you're not going to have a memorable hot dog experience using the same toppings as everyone else. This is where the secret ingredient comes in. A secret sauce, if you will.

Only thing is, it isn't secret at all.

That's right. Arby's Horsey Sauce. Put it on a hot dog and it'll change your life. There's something about the tart yet smooth flavor that compliments a hot dog perfectly. Now before you get all grossed out or think I'm a crazy person, try it. Trust me. It's so good. Best part is, if you don't like it, and least that little sauce packet was free!

Want to try your hand at some homemade Horsey Sauce? Want to spice it up a bit more? Here's how to make it.
