In-N-Out Burger Spread Dipping Sauce (Copycat)

"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."
