Freddie’s Frozen Custard & Steakburgers is a casual fast-food restaurant chain based in Wichita, Kansas. It is known for their steakburgers, Vienna beef hotdogs, and chicken sandwiches. Of course, frozen custard for dessert is a must to go with your sandwiches. But, don’t forget the fries as well. Most of us enjoy dipping our fries in a sauce, and Freddie’s has a sauce just for fries. The delicious sauce needs only 5 ingredients. Ketchup, mayonnaise, vinegar, black pepper, and salt. Simple but satisfying. But they also have powdered steakburger and fry seasoning, just thought it should be mentioned.
