Combine the base ingredients: In a medium mixing bowl, add the mayonnaise and ketchup. Whisk them together until completely smooth and evenly blended, making sure there are no streaks of white or red left in the mixture.
Add seasonings: Pour in the Worcestershire sauce, then sprinkle in the garlic powder, black pepper, paprika, and salt. Whisk slowly and thoroughly so the spices are evenly distributed throughout the sauce, creating a creamy and lightly speckled appearance.
Adjust flavor: Taste the sauce and adjust seasoning if needed. Add a pinch more black pepper for extra bite or a small pinch of salt if you prefer a slightly bolder flavor. Stir again until fully incorporated.
Chill for best flavor: Cover the bowl with plastic wrap and refrigerate for at least 2 hours before serving. This resting time allows the flavors to meld together and develop that signature Raising Cane’s taste. For the most authentic result, refrigerate overnight.
Serve: Before serving, give the sauce a quick stir. Serve chilled as a dipping sauce for chicken tenders, fries, burgers, or sandwiches.
