Culver's Signature Sauce is a rich and creamy condiment with a unique blend of tangy buttermilk, Parmesan cheese, and a hint of blue cheese, offering a versatile and dreamy flavor profile ideal for enhancing a variety of dishes.
In a medium-sized bowl, mix the mayonnaise and buttermilk. You should add the mayo first and the buttermilk second. Mix them well, but be careful not to go overboard with it so as not to overly thin the mixture.
Add the grated parmesan cheese to the buttermilk-mayo mixture and mix again until the cheese homogenizes with the mixture.
Next, add the cheese crumbles and mix gently. The cheese crumbles will create a lumpy texture, which you can't even out. So, don't try to smoothen it out.
Season the sauce with garlic powder, onion powder, salt, and pepper. Mix gently to disperse the seasoning equally through the sauce.
Give the sauce 10 minutes to settle and the flavors to meld. Cover it with a plastic wrap and pop it in the fridge. Remember, it contains perishables, so don't keep it at room temperature.
