Here is how to make a very similar Raising Cane's sauce for all your fried chicken needs. Although their sauce recipe is a highly-regarded secret, this recipe comes close! Here are the ingredients:
1/2 cup mayonnaise
1/4 cup ketchup
1/2 teaspoon of garlic powder
1/2 teaspoon of black pepper
1/4 teaspoon Worcestershire sauce
Can you tell the difference between the two sauces at the end?
