Blend IngredientsCombine 1 cup of water, ½ cup of ketchup, 2 tablespoons of brown sugar, ¼ cup of white vinegar, ¾ teaspoon of garlic salt, ½ teaspoon of paprika, 3 tablespoons of Worcestershire sauce, and ⅛ teaspoon of cayenne pepper in a blender.Blend these ingredients on high speed until they are thoroughly combined and the mixture is smooth.

Cook The SaucePour the blended mixture into a small saucepan.Heat the saucepan on medium-low heat for 20 minutes, stirring occasionally to prevent the sauce from sticking or burning.

Thicken The SauceIn a small bowl, prepare the thickening mix by combining 1 tablespoon of cornstarch with 2 tablespoons of water.Add this thickening mix into the saucepan and stir well to integrate it into the sauce.

SimmerAfter adding the thickening mix, reduce the heat to low.Let the sauce simmer for an additional 10 minutes. This helps to thicken the sauce and meld the flavors together.

CoolingRemove the saucepan from the heat.Allow the sauce to cool completely before serving. This step is crucial for the sauce to reach its ideal consistency and flavor profile.

StorageOnce the sauce is cooled, transfer it to a covered container.Store the sauce in the refrigerator.This recipe should yield a tangy, slightly spicy sauce similar to Arby's original, perfect for sandwiches, dips, or as a condiment for various dishes.
