In-N-Out Burger Animal Sauce Copycat Recipe

"In-N-Out Burger Spread is the delicious "secret" sauce that is used on all burgers and topped on Animal Style Fries. Easy to make and tastes exactly the same! In-N-Out Burger Spread may sometimes be confused with regular 1000 Island dressing but the truth is that with just a few ingredients you can have an actual honest to goodness copycat. I should know something about these copycats, I actually made this dipping sauce as part of my original In-N-Out copycat posts. But then I would get emails asking if I was going to share the sauce recipe (it was in the post, just not highlighted enough)."
