Ingredient	Purpose
Ketchup	The base that provides sweetness and tanginess
Hot sauce	Adds a mild kick without overwhelming the flavor
BBQ sauce	Delivers smoky depth and a rich, molasses-like note
Vinegar	Offers acidity to balance out the sugars and boost shelf life

How to Make Authentic Chicago Mild Sauce

You won’t need any special tools or techniques—just a stovetop, a pan, and a blender. The secret to perfect mild sauce is balance: not too sweet, not too spicy, and not too thick. Here’s how to nail it every time.

Step-by-Step Instructions

1. Combine your base ingredients: In a saucepan, add ketchup, BBQ sauce, hot sauce, vinegar, sugar, and a pinch of salt.
2. Add your dry seasonings: Stir in garlic powder and paprika for added depth.
3. Simmer gently: Bring the mixture to a low simmer over medium heat. Stir frequently to prevent sticking.
4. Adjust consistency: If the sauce seems too thick, add a little water until it reaches a smooth, pourable texture.
5. Optional step: Add red food coloring if you want that signature look found in Chicago joints.
6. Chill for 10 minutes to set: Let the sauce rest and thicken slightly while the flavors meld together.
7. Store and serve: Cool completely before transferring to a squeeze bottle or jar. Keep refrigerated and use within two weeks.
