🍔 What's In-N-Out Burger

For those of you that have never heard of In-N-Out Burger, it's a California-based family-owned Burger restaurant chain founded in 1948. It has the honor of being California's first drive-thru hamburger stand. I think recently they've even expanded to Arizona.

The In-N-Out Cheeseburger is made of a Beef Patty, Onion, Lettuce, Tomato, Cheese Slice and this sauce on a Toasted Bun. Now you can make your own at home with this wonderful recipe.

One of the benefits of making this awesome burger sauce at home is you won't have to wait in line! If you've been to In-N-Out Burger before, you know exactly what I mean.

This sauce is so good I also like to put it on my hot dogs. For more great recipes like this one, make sure you check out my collection of Condiments, Sauces & Rubs Recipes.
